What to Wear in Los Angeles in December: 10 Top Outfits

By Sofia Laurent — Fashion Editor & Stylist

Everyone packs wrong for LA in December. I've watched it happen — luggage rolling off the carousel stuffed with heavy wool sweaters and thermal underlayers, and then the doors open and it's 68°F, the sky is that specific shade of cloudless blue the city patents every winter, and the bougainvillea is still rioting over every stucco wall like it missed the memo about the season. Los Angeles in December does not want your caution. It does not want your safe navy cardigan or your sensible grey coat. What it rewards — actually rewards, in the way that good light rewards good color — is confidence. Bright, saturated, unapologetic confidence.

I've been traveling between London and LA for work since 2019, mostly for shoots and fashion weeks and the occasional editorial project, and every December the lesson is the same: the women who look best here are the ones who wore what they actually wanted. Not what winter told them to wear. These 15 looks are built around that idea. They cover everything from a Saturday morning in the Arts District to a late-night warehouse party, and the one thing they share is color. Real color. The kind that photographs beautifully in that low amber afternoon sun and holds its own indoors under the flat overhead lights of a holiday dinner.

The Case for Going Full Yellow

Canary yellow is not a summer-only color. It's a light-quality color — meaning it responds to how light falls on it, and the low, golden December sun in Southern California is genuinely one of the best environments on earth for wearing it. Stronger than summer's overhead glare, warmer than spring's flat brightness. The light in LA in December makes yellow look like intention.

The canary yellow wrap midi dress with cream mules is the outfit that started this whole conversation for me. I wore almost this exact combination — yellow wrap dress, barely-there cream heels, single gold chain — to a rooftop dinner in Silver Lake last December. Someone at the next table leaned over mid-appetizer to ask if the dress was vintage Pucci. It was a £60 find from an online mid-season sale. But here's the trick: the wrap silhouette does something genuinely remarkable in that specific quality of California evening light. The fabric drapes across the body rather than clinging, which means it's flattering across a wide range of shapes — pull the tie slightly higher at the waist to emphasize a longer torso, or let it sit at the natural waist to balance proportions without any structural work required from the garment itself. Cream mules keep the palette effortless. Cream mules in a block or kitten heel are the single most-used shoe in my December LA wardrobe. Don't add a bag in a contrasting color here — ivory, nude leather, or natural woven only. Let the yellow breathe.

Pro tip — keep your undergarments seamless and either skin-toned or matching the dress. Wrap dresses have a habit of revealing exactly what's underneath when the breeze moves through them. There is always a breeze in LA.

A second take on yellow, this wrap dress leans into a more fluid, Mediterranean glamour — slightly more movement in the skirt, a silhouette that photographs beautifully when you're walking rather than standing still. Vogue's fashion editors have consistently noted that wrap dresses perform better across body types than almost any other silhouette precisely because the diagonal line created by the wrap front is inherently elongating and the waist definition is adjustable. Simple sandals or low block heels finish this one. That's it. December in LA is genuinely warm enough that this isn't even brave — it's just practical.

Now the canary yellow satin midi slip dress is a different proposition entirely. This is evening. This is the warehouse party or the sprawling gallery opening where the DJ is too loud and the lighting is deliberately low and you want to be the person someone describes to their friend the next morning. Satin at midi length reflects light differently at every angle, so even the smallest movement reads as deliberate. The trick with satin is to pair it with matte everything else: matte shoes, matte bag, minimal makeup. One shiny surface at a time. If you're shopping around, satin midi slip dresses on Amazon cover a wide range of price points — look for a bias-cut option if you can, which hangs more gracefully than a straight-cut satin and skims rather than clings.

Cobalt Blue and the Art of Looking Effortlessly Overdressed

If yellow is the color of LA sunshine, cobalt blue is the color of its pool water. Rich, saturated, unapologetic. And December — strangely — is when cobalt looks its best. The clear winter sky in Southern California is a slightly cooler shade of blue than summer's haze-softened version, and cobalt sits against it like it was designed for exactly this context.

The cobalt blue power blazer-and-trouser set worn head-to-toe is one of my absolute favorites in this entire edit. The mistake most people make with a matching set is breaking it up unnecessarily: a contrasting belt, a white button-down underneath that fragments the clean line, a bag in a competing color. Don't. When you wear a matching set as a single coherent unit, proportions work in your favor regardless of height. Taller figures can try a wide-lapel blazer with a slightly cropped trouser that shows the ankle — the proportion game there is excellent. Petite frames should opt for a longer blazer that creates a continuous vertical line, which reads as height rather than taking it away. Both approaches work. This set moves comfortably between holiday dinners, gallery openings, and a well-lit afternoon meeting — cobalt registers as authoritative in professional contexts in a way that most bold colors don't quite manage.

I had a proper cobalt moment at a gallery opening in Venice Beach about a year ago — one of those sprawling white-walled spaces in a converted warehouse where the art is ambitious and the wine is exactly acceptable. I wore a cobalt satin blazer with a matching slip skirt, a secure bralette in the same shade underneath, and a single yellow-gold chain at the throat. Two different people asked me who it was. I told them it was a sample. (It wasn't.) The point is: the cobalt satin blazer-and-slip-skirt combination does something a regular suiting set can't. Satin cuts the formality of the structure; the matching color creates visual coherence; the slip skirt allows actual movement in a way that trousers don't. This is your December after-party outfit — the one you reach for when the dinner ends and someone suggests going somewhere else and you want to arrive already looking like you planned for it.

The belted cobalt blue wool coat is for the moments when LA actually asks for outerwear — early mornings in the canyon, evening walks near the ocean where the temperature drops ten degrees in twenty minutes, any stretch of the 101 at 7am. Belt it at the waist, always. A loose, unbelted wool coat swallows the silhouette; belted, it becomes architectural. Pair it with slim trousers or straight-leg jeans and a pair of ankle boots that can actually handle real walking — cobalt this saturated doesn't need accessories competing for attention. Keep the rest quiet.

Fuchsia Refuses to Be Ignored

Fuchsia is not subtle and it is not trying to be. In Los Angeles, where the streets are wide and the buildings are low and the sky is enormous, a fuchsia outfit doesn't overwhelm the surroundings — it communicates with them. The city has the scale for it.

The fuchsia pink moto jacket over relaxed wide-leg trousers is weekend dressing done right. This works for every body type because the proportional logic is sound: the structured, slightly boxy shoulder of a moto jacket is balanced by the width at the hem of the wide-leg trouser, creating a balanced silhouette without anything actually being fitted. The jacket provides the interest; the trousers provide the foundation. Keep whatever's underneath very simple — a fitted white or black tee, nothing printed, nothing that competes. The jacket is talking loudly enough. One small change that genuinely elevates the whole look: roll the jacket sleeves up once, just to mid-forearm, so the sleeve detail doesn't overwhelm a shorter arm.

The fuchsia pink sequined mini dress. Which is exactly what it looks like and does exactly what you think it will. An outdoor concert, a rooftop bar, the December holiday party where you've already RSVPed twice — this dress exists for moments when you want to walk in and have the room recalibrate slightly. Harper's Bazaar has long made the case that bold, joyful dressing is its own form of sophistication, and this dress is the most direct evidence of that argument I know. Styling it is almost beside the point, but: keep your shoes simple. Clear heels, metallic strappy sandals, a barely-there flat. The dress is the entire look. Don't layer necklaces. Don't layer anything. LA December nights are mild enough that you genuinely don't need a jacket, and a jacket over sequins at a concert is a tragedy.

That said — if the evening cools down unexpectedly, a long black or ivory cardigan thrown over sequins is a surprisingly effective combination. A great knit cardigan earns its place in any travel capsule for exactly this kind of moment.

The fuchsia pink cropped knit sweater with flowy wide-leg trousers is the quieter, more accessible version of fuchsia — softer in energy, easier to style, and genuinely appropriate for everything from a late brunch in Los Feliz to an afternoon walk through the Farmer's Market. Tuck the front hem of the sweater just slightly — not a full tuck, just a small forward fold at the center front, leaving the sides and back loose. This is the move that defines the waist without making the look feel stiff or contrived. The wide-leg trouser should stay in a neutral: ivory, cream, warm white, light tan. Fuchsia and ivory is a particularly successful pairing because the warmth of the pink reads against the cool of the white in a way that feels deliberate rather than accidental — color theory in very practical action.

Why Emerald Green Is the Most Underrated December Color

Ask most people to describe December dressing and they'll reach for red, gold, maybe burgundy. Emerald green is the one that keeps getting overlooked — which is exactly why you should wear it. It reads as festive without being costume-y, it works under every lighting condition from outdoor afternoon sun to dim indoor warmth, and it photographs beautifully against almost any background LA can offer.

The emerald green satin slip dress layered with an open ivory cardigan is one of the most romantic outfit combinations I've put together in recent memory — and the reason it works is a fabric contrast that seems counterintuitive until you see it in person. Satin is liquid and reflective; knit is textural and matte. The matte cardigan grounds the slip dress and keeps it from reading as purely lingerie-inspired; the slip dress gives the cardigan a reason to be interesting rather than just warm. For LA December evenings — dinners in Malibu, sunset drinks in Santa Monica, anything with a view — this is the formula. Keep the cardigan open and untied; don't belt it over the dress, don't button it closed. Let both pieces coexist. Heeled sandals or kitten heels work best here; you want the hemline of the slip dress visible rather than lost in a boot shaft. If you love the cardigan-over-dress concept, there's genuinely a whole world of layering possibilities with the right knit cardigan worth exploring.

I wore the emerald blazer over straight-leg jeans and white leather sneakers to a Saturday morning in the Arts District last December — the kind of aimless morning that turns into six hours of wandering between coffee shops and galleries. Three separate people asked where the blazer was from that day, which tells you something real about how emerald reads in actual daylight. The key is the fit: relaxed, not oversized. Not structured corporate suiting, but not swimming in fabric either. Roll the sleeves once to mid-forearm — not to the elbow, which reads as doing yard work — and leave the front unbuttoned. Straight-leg or wide-leg jeans both work; what matters is that the jeans have a clean line at the hem. White sneakers, styled with some intentionality, finish this look in a way that keeps it relaxed without becoming sloppy. This is the outfit for brunch, for afternoon shopping, for the casual lunch that turns into a four-hour event. Emerald holds its color under indoor fluorescent light in a way that most bold colors don't — you'll look just as intentional inside as you did leaving the house.

Tangerine and Red: The Warm Tones That Actually Feel Like December

Here's where the festive energy stops being subtle.

The tangerine orange ribbed mock-neck sweater tucked into cream trousers is the most wearable outfit in this entire piece — the one that requires the least planning and delivers the most reliable result. Ribbed fabrics earn their keep here: the vertical texture creates a slimming line regardless of how fitted the knit actually is, which makes ribbing more forgiving than most people realize. The mock neck is also doing specific work — it elongates the neck beautifully and gives the neckline a finished, intentional look without the effort of a scarf. For the tuck: push the sweater fully into the waistband at the front and sides, then pull a small amount back out at the back for comfort and ease of movement. Who What Wear has covered the French tuck extensively and it genuinely is the one styling trick worth practicing in a mirror. Cream trousers neutralize the intensity of tangerine without competing with it — that warmth-on-warmth pairing is the reason this reads as festive rather than aggressive.

The structured tangerine blazer with tailored ivory trousers makes the same color logic more architectural — this is for work, for lunch meetings, for any context where you want to look authoritative without the formality of black or navy suiting. Keep everything outside the blazer deliberately neutral: ivory trousers, nude or cream shoes, a simple gold earring if anything at all. The mistake most people make with an oversaturated color blazer in a professional setting is adding more — a printed silk square in the pocket, a statement necklace, a patterned shirt underneath. Don't. The blazer is communicating on your behalf. Let it. For more office outfit ideas that commit to color without sacrificing polish, there's a genuinely useful guide to bold work dressing that's worth bookmarking.

The fire-engine red power coat and trouser set is uncompromising. Red head-to-toe reads as bold in any city; in LA's December light, it reads as inevitable. What makes monochromatic red work where it might overwhelm in other contexts is the specificity of the shade — fire-engine red sits at exactly the right warmth to work against both cool and warm complexions, which can't be said for every shade of red. The mistake most people make with a red-on-red look is over-accessorizing to "balance" it: a printed scarf, a mixed-metal necklace, a patterned bag. Stop. Red balances itself. Simple black or nude shoes, one minimal clutch, and the confidence to walk into the room knowing you're wearing the most deliberate outfit there. That's the whole formula.

The fire-engine red wrap dress is softer in energy than the coat-and-trouser set but no less impactful. Wrap dresses in saturated colors work across such a wide range of body types precisely because the adjustable tie allows you to define or soften the waist entirely on your own terms — tighter if you want definition, looser if you want ease. The warm undertones in fire-engine red come alive in golden-hour light, and LA delivers that light even in December, particularly in the hour before sunset when the whole city turns amber. This is the dress for holiday dinners, end-of-year parties, the kind of evening where someone takes a photo and it actually looks the way the moment felt. Red wrap dresses at midi length — hitting at or just below the knee — give the most balanced proportions if you're wearing flats, while a maxi works beautifully with a small heel.

Building Your Own LA December Wardrobe

So what does all of this actually tell you? A few things I'd stake a full wardrobe on.

The wrap silhouette — in a dress, in a coat, in anything with an adjustable tie — solves more fit problems before they start than any other design detail in fashion. If you own one wrap dress that fits you well, you're already more dressed for LA December than most of what's in the average suitcase. The adjustable waist, the diagonal neckline, the forgiving drape — these are structural advantages, not aesthetic ones.

Fabric contrast is the secret weapon of the most interesting outfits here. Satin against knit. Structured blazer against fluid trousers. Sequin against plain. The contrast is what creates visual depth; without it, even expensive clothes can read as flat. And don't underestimate the power of a single bold color worn head-to-toe. Monochromatic dressing in a saturated shade — cobalt, red, even tangerine — creates a more powerful impression than a mixed outfit at a fraction of the effort.

Finally: LA December is genuinely warm enough to wear almost everything on this list without a heavy layer underneath. Trust the forecast. Pack light. And go bolder with color than you think you should — the light there will make you look right.

What's your December LA go-to? The rule I keep coming back to, after all these years of getting it wrong in wool coats and getting it right in satin and blazers, is this: Southern California in winter doesn't ask for restraint. It asks for warmth — in color, in fabric, in the way you walk into a room.
