Los Angeles in December brings a relaxed mix of sunny afternoons, cooler mornings, and crisp evenings.
When planning what to wear in Los Angeles in December, I love combining effortless California style with practical layers that work across the city.
Think denim, cozy sweaters, casual dresses, sneakers, ankle boots, and a lightweight jacket.
These Los Angeles outfit ideas, December packing tips, and versatile winter looks will keep you comfortable from beach walks to dinner in the city.
1. The Relaxed Denim Jacket and Striped Sweater
Need an outfit that can handle cool air, bright sun, and a long walk?
Layer a striped sweater under a relaxed denim jacket for an easy coastal uniform.
The knit adds warmth, while denim blocks light wind without feeling heavy.
This combination works for pier walks, outdoor cafés, casual shopping, and breezy afternoons near the water.
Outfit Pieces:
– Relaxed denim jacket in medium blue or ecru (roomy enough for a sweater)
– Navy-and-cream striped sweater (cotton or lightweight wool blend)
– Straight-leg jeans in faded blue or soft white (high or mid rise)
– Low-profile sneakers or suede ankle boots (white, tan, or chocolate)
– Canvas tote and tortoiseshell sunglasses
Styling Tips:
– Choose a jacket with space through the shoulders so the sweater does not bunch.
– Add a loose front tuck to create shape while keeping the outfit relaxed.
– Match brown boots with a leather belt or bag for a warmer finish.
– Roll the jacket sleeves once to show a watch or slim bracelet.
– Use moisture-friendly sneakers if your route includes wet sand or sea spray.
This look moves easily from Santa Monica shops to the beach path.
Swap the sneakers for ankle boots when the morning feels cooler, or choose olive corduroy pants for extra texture.

A slip dress does not need to stay in your summer wardrobe.
Add a soft cardigan, and the silky shape becomes comfortable for a mild December day by the ocean.
The smooth dress against plush knitwear creates a pleasing texture contrast, while the flowing fit keeps you cool when the sun appears.
Wear this combination for lunch dates, gallery stops, sunset walks, or casual holiday gatherings.
Outfit Pieces:
– Midi slip dress in sea-glass green, clay, cream, or faded blue (satin or washed cotton)
– Lightweight chunky cardigan (oatmeal, camel, or soft charcoal)
– White leather sneakers or flat sandals (low ankle boots for more coverage)
– Small gold hoops and a woven shoulder bag
– Optional fitted tank under a low-cut dress
Styling Tips:
– Pick a cardigan that ends near the upper thigh if the dress is fitted.
– Wear it open during warm hours, then button two middle buttons as the breeze rises.
– Keep the dress hem below the knee for easier movement on the boardwalk.
– Repeat one dress color in your bag or shoes to make the outfit feel connected.
– Carry a cotton scarf inside the tote for extra warmth after sunset.
The result feels feminine without looking too delicate.
Trade sneakers for flat leather sandals on warmer afternoons, or add ankle boots when you want a stronger December finish.

3. The Oversized Shacket with Wide-Leg Pants
An oversized shacket gives you jacket coverage with the softness of a shirt.
Pairing it with wide-leg pants creates a relaxed silhouette that feels modern and comfortable for December beach days.
The look handles changing temperatures well, making it useful for Venice Beach walks, outdoor markets, casual meetups, and coffee near the shore.
Outfit Pieces:
– Oversized shacket in brushed cotton, corduroy, or light quilting (faded teal, tan, or charcoal)
– Fitted ribbed tank or close-cut long-sleeve top (cream or black)
– High-waisted wide-leg pants (washed denim, oat cotton, or black twill)
– Chunky sneakers or lug-sole ankle boots
– Small crossbody bag worn under the shacket
Styling Tips:
– Keep the base layer fitted so two roomy pieces do not overwhelm your shape.
– Button only the middle of the shacket to suggest a waist while leaving the hem loose.
– Choose a higher trouser waist for a longer, cleaner leg line.
– Cuff the sleeves once to reveal a watch or narrow bracelet.
– Keep your colors muted, using one coastal shade instead of several bright tones.
This outfit feels creative without becoming complicated.
Choose canvas slip-ons for a lighter look, or switch to lug boots when the sky turns gray and the sand feels cool.

A knit polo gives casual beach dressing a sharper shape without making you feel overdressed.
Soft cargo pants keep the outfit practical, while clean sneakers make it ready for long walks and busy days.
The balance works for coffee runs, Santa Monica Pier, outdoor shopping, and lunch by the water.
Outfit Pieces:
– Short-sleeve knit polo (cream, navy, olive, or warm gray)
– Thin long-sleeve tee or fitted camisole underneath
– Soft cotton cargo pants (stone, faded olive, or navy)
– Supportive white or cream sneakers with grippy soles
– Canvas tote, simple sunglasses, and ribbed ankle socks
Styling Tips:
– Choose a polo that skims your body instead of clinging across the chest.
– Leave the polo untucked with higher-waisted cargos, or add a small front tuck.
– Keep cargo pockets mostly empty so the trousers retain a smooth line.
– Let only a little sock show above the sneakers for a neat finish.
– Add a lightweight scarf when the forecast calls for strong coastal wind.
This outfit feels sporty, tidy, and easy to wear.
Replace the cargos with straight chinos for a cleaner look, or use leather slip-ons when your day includes dinner after the beach.

A denim midi skirt gives you more coverage than shorts while keeping the easy spirit of a beach outfit.
Add a fine knit sweater and ankle boots, and you have a comfortable look for cooler paths, casual dates, and coastal markets.
The sturdy denim contrasts nicely with soft knitwear, creating a feminine shape that still feels practical.
Outfit Pieces:
– Medium-wash denim midi skirt with front slit or back vent
– Fine-knit sweater in oatmeal, washed blue, pale sage, or faded lavender
– Flat leather ankle boots (black, tan, or chocolate)
– Soft shoulder bag with room for sunglasses and sunscreen
– Optional opaque socks or thin tights
Styling Tips:
– Test the slit before leaving home so you can take a full walking stride.
– Tuck the sweater fully into a high-waisted skirt, or use a small front tuck with a relaxed knit.
– Pick boots with an almond or rounded toe to keep the mood casual.
– Add a cropped jacket rather than a long coat, which can hide the skirt shape.
– Repeat the boot color in your belt or bag for a balanced finish.
This outfit suits a Malibu lunch, a casual date, or a windy afternoon outdoors.
Swap boots for low-profile sneakers when the beach is dry, or add thin tights for extra warmth.

Cream, sand, and warm beige create a calm color story that looks natural beside the ocean.
The secret is to mix textures instead of searching for an exact color match.
Ribbed knitwear, cotton twill, canvas, and suede give the outfit depth while keeping it soft enough for brunch, photos, shopping, or a slow beach walk.
Outfit Pieces:
– Cream wide-leg jeans, trousers, or a long denim skirt
– Sand-colored ribbed long-sleeve top
– Cropped camel jacket or mushroom cardigan
– Tan suede sneakers, white trainers, or muted gray flats
– Woven tote with leather handles and brown sunglasses
Styling Tips:
– Mix warm and cool neutrals so the palette does not look flat.
– Choose different layer lengths, such as a hip-length top over longer trousers.
– Add one small coastal accent through a blue scarf, striped sock, or bag lining.
– Use a darker shoe when the outfit feels too pale.
– Keep jewelry simple, with one gold chain or a pair of small silver hoops.
This formula feels clean but never stark.
Add a denim jacket for more contrast, or replace the sneakers with tan loafers when your beach plans include a nicer restaurant.

7. The Scarf-Layered Sweater and Straight Jeans
A lightweight scarf can make a simple sweater and jeans outfit feel warmer, brighter, and more finished.
It adds color near your face without the bulk of a thick winter wrap.
The combination works especially well for chilly Venice mornings, boardwalk walks, coffee stops, and plans that stretch into the evening.
Outfit Pieces:
– Crewneck sweater in oatmeal, navy, burgundy, or washed green
– Straight-leg jeans in medium blue or soft black
– Cotton, modal, or thin wool scarf (small stripe, check, or faded geometric print)
– Supportive sneakers or flat suede ankle boots
– Canvas tote and simple watch
Styling Tips:
– Try a loose knot, single drape, or simple loop instead of wrapping the scarf tightly.
– Match one scarf color to your bag, shoes, or sunglasses for a quiet connection.
– Use a plain sweater when the scarf has a bold pattern.
– Choose straight jeans with enough room for thin socks without bunching.
– Select a soft fabric and check it against your neck before a long walk.
This outfit is easy to adjust as the temperature changes.
Tuck the scarf into your tote after sunrise, or trade sneakers for ankle boots when your beach walk becomes an evening dinner plan.

When your beach day includes biking, walking, or an outdoor workout, a lightweight windbreaker keeps the outfit useful without making it look overly technical.
It blocks ocean air, folds into a tote, and layers easily over simple basics.
The style works for Santa Monica paths, casual errands, beach volleyball, and active meetups.
Outfit Pieces:
– Matte lightweight windbreaker (cream, faded blue, soft black, or muted coral)
– Straight-leg joggers, relaxed leggings, or soft utility pants
– Long cotton tee, fitted tank, or thin sweatshirt
– Cushioned sneakers with reliable grip
– Baseball cap, compact crossbody bag, and simple sunglasses
Styling Tips:
– Choose a jacket with room for one thin layer, not a bulky hoodie.
– Pair leggings with a longer tee that covers the hip for balanced proportions.
– Push the sleeves slightly up when the breeze is mild.
– Keep color-blocking limited to one small panel or trim detail.
– Add a neat ponytail, slim watch, or small gold hoop for a polished touch.
This outfit captures the active side of coastal California style.
Replace joggers with relaxed utility pants for more structure, or carry a canvas tote with a beach blanket for a slower afternoon.

A linen-blend blazer gives casual denim a polished lift while staying light enough for mild December weather.
Choose an unstructured cut, then soften it with a tee, knit top, or ribbed tank.
This mix works for Malibu restaurants, gallery visits, beachside meetings, and lunch plans that continue into the afternoon.
Outfit Pieces:
– Unstructured linen-blend blazer (cream, tobacco, faded navy, or soft gray)
– Soft white tee or thin ribbed knit top
– Straight jeans, cropped relaxed denim, or a denim maxi skirt
– Leather sneakers, woven flats, or low ankle boots
– Roomy tote with a firm base
Styling Tips:
– Leave the blazer open so it feels casual rather than office-ready.
– Push the sleeves up to show a slim bracelet or the jacket lining.
– Pick a slightly faded tee instead of a crisp button-up shirt.
– Use a small front tuck to define the waist with straight jeans.
– Add one handmade-looking accessory, such as a woven belt or raffia bag.
The outfit feels grown-up without losing its beach ease.
Switch sneakers for woven flats when you want a dressier finish, or add a lightweight scarf if the wind picks up.

A soft utility vest adds warmth around your middle while leaving your arms free.
That makes it useful for mild December weather, when shade feels cool but direct sun feels warm.
Layer it over knitwear for beach blankets, Malibu walks, casual errands, and relaxed outdoor lunches.
Outfit Pieces:
– Lightweight utility vest in quilted cotton, brushed canvas, or nylon (olive, tan, or cream)
– Fine-knit sweater or long-sleeve henley in faded blue or oatmeal
– Straight jeans, corduroy pants, or a soft denim skirt
– Suede sneakers or flat ankle boots
– Small crossbody bag and optional lightweight scarf
Styling Tips:
– Pick roomy armholes so the sweater does not pull across your shoulders.
– Pair a cropped vest with high-waisted bottoms for a clear waistline.
– Let a longer vest fall over a slimmer base to avoid extra bulk.
– Use the pockets for lip balm and keys, but keep heavy items in your bag.
– Add soft footwear to balance the vest’s practical shape.
This outfit has a useful edge without looking rugged.
Wear it open over a thin knit, or replace the jeans with corduroy pants when you want more texture and warmth.

A knit set makes dressing quick, but a longline coatigan gives it enough structure for public plans.
Smooth rib knit or jersey feels soft for sitting on a beach blanket, while the outer layer adds movement and warmth.
This outfit suits café stops, Santa Monica walks, casual shopping, and relaxed lunches.
Outfit Pieces:
– Matching knit top and trousers in oatmeal, heather gray, faded navy, or cocoa
– Wide-leg or straight-leg knit pants (secure waistband)

A sweater vest gives a button-up shirt a relaxed preppy twist that feels fresh near the beach.

A sunset beach plan needs one layer that can handle the quick drop in temperature.
Smooth fleece, a brushed overshirt, or a thin fleece-lined jacket adds warmth without the bulk of a winter coat.
Combined with denim and boots, it works for Venice sunsets, casual dinners, boardwalk walks, and evenings that last longer than planned.
Outfit Pieces:
– Smooth fleece pullover or brushed overshirt (cream, dusty rose, sea blue, or charcoal)
– Fitted thermal tee or long-sleeve base layer
– Straight jeans, relaxed carpenter jeans, or denim midi skirt
– Flat ankle boots with practical soles
– Large woven tote, cotton scarf, and optional striped beanie
Styling Tips:
– Choose an outer layer that closes fully at the front when the wind rises.
– Keep the hem short enough that it will not drag through sand.
– Use a fitted thermal under a roomy fleece to control the proportions.
– Wear boots for cool sand, or clean sneakers if you stay on the boardwalk.
– Pack extra socks and a small thermos in the tote for longer evenings.
This outfit brings cozy winter comfort without heavy coats or bulky accessories.
Swap boots for sneakers during the day, then add the scarf when the sun drops and the coastal air turns noticeably cooler.
