Clothing

Insulated coat or wool jacket
Las Vegas December lows hit 38°F — New Year's Eve crowds on the Strip stand outdoors for 4–6 hours waiting for midnight fireworks in cold that many visitors from warmer climates are completely unprepared for.
Layering sweaters and thermals
December casino interiors at 68°F contrast with outdoor temperatures as low as 38°F — thermal underlayers keep you warm on the Strip while providing the base for removing layers once inside the Bellagio or Caesars Palace.
Dressy holiday outfit
New Year's Eve at Las Vegas venues — from Zouk at Resorts World to Drai's at the Cromwell — requires polished party attire; the biggest NYE shows in the city have dress codes that go well beyond smart-casual.
Jeans and casual daywear
December Las Vegas is quieter between Christmas and New Year's — daytime temperature at 57°F is comfortable for leisurely Strip walking, and jeans with layers cover most daytime activities in a pleasant, uncrowded environment.
Comfortable loungewear for hotel evenings
Las Vegas December cold evenings at 38°F make the hotel room more appealing than usual — comfortable loungewear for non-event evenings during a multi-day holiday stay is worth packing for a week-long trip.

Footwear

Warm, cushioned walking boots or sneakers
New Year's Eve on the Las Vegas Strip means standing on hard concrete in 38°F cold for several hours — insulated, cushioned footwear prevents both cold feet and knee pain from extended outdoor standing at the Bellagio and MGM Grand viewing areas.
Dressy heeled boots
Las Vegas NYE venue parties at major clubs require dressed-up footwear — dressy ankle or knee boots handle both the 38°F outdoor temperature and the upscale NYE dress code simultaneously.
Casual flat shoes for daytime
December daytime at 57°F is pleasant for slow Strip strolling and indoor shopping at the Grand Canal Shoppes — comfortable flats work for the unhurried pace of Las Vegas's quieter mid-December weekdays.

Accessories

Scarf and warm hat or ear warmers
New Year's Eve crowds on the Las Vegas Strip stand in 38°F open-air conditions — Bellagio and MGM Grand fireworks viewing zones have no overhead shelter, making head and neck warmth critical for the midnight countdown.
Insulated gloves or touchscreen gloves
Las Vegas NYE requires constant phone use for photos and coordination in 38°F temperatures — touchscreen-compatible gloves let you operate your phone without exposing hands to cold desert night air for extended outdoor periods.
Sunglasses
Las Vegas December skies are mostly clear and desert UV at 2,001 ft elevation still produces meaningful glare — bright December afternoons on the Strip between Mandalay Bay and the Wynn require eye protection even at the year's lowest UV levels.
Compact crossbody bag
New Year's Eve on the Las Vegas Strip packs 400,000+ people into a few blocks — a compact crossbody with a secure zip closure is the safest way to keep essentials accessible in extremely dense, slow-moving crowds.
