Quick answer
Do People Dress Up for New Year's in Antarctica?
New Year's Eve on an Antarctica cruise is usually festive but still expedition-casual. Bring one comfortable nicer outfit if your sailing includes a celebration, but do not sacrifice warm layers or waterproof gear for formalwear.
Before departure
Check your ship’s holiday and dining guidance. One suitable casual outfit is often enough; keep excursion layers and waterproof gear as the packing priority.
