We'll be sailing the Western Caribbean on Imagination for New Years. Coming from the Cold Cold North (Montreal Canada), my Holiday dress wear consists of long sleeves and velour. Not appropriate for the Caribbean? Feels strange to think of sleeveless summery prints in Dec./Jan. but is this more practical? Just don't know what to expect! Thanks for any input.... Donna.
Even though your cruise is to the Caribbean, people will wear typical New Year's eve finery; silk, satin, beads, velvet, strapless or thin straps, long sleeves, short or long gowns/dresses, pants ensembles, etc. It is often cool in public rooms on board ship. The evenings activities are usually all in side. You will appreciate your long sleeve outfits. The only evening/seasonal accessory may be your shoes. Strapy sandals will work well.
It will still feel plenty warm down there even for New Years hopefully, so be sure to pack your summer wear stuff for days on the ship and going to ports, shorts, t-shirts and a few bathing suits. Enjoy the sunshine!
The evenings in the Caribbean usually are quite warm (low temperatures around 70 degrees Fahrenheit or 21 degrees Celsius). Although winter formalwear most certainly is proper, you might find it a bit warm. Consider wearing whatever you would wear to a formal wedding in July instead.
