NO wrong, bring summer style clothing. When you leave even though it will be december the weather in the Caribbean will be in the mid 80s-early 90s. Personally i'd bring a few 2-3 pairs of shorts (girls might sub 1 or 2 shorts for skirts), 2 pairs of boardshorts (for guys u kno we wear these just like shorts), like 2 pairs of jeans and my suit for formal night(s). As for shirts usually like 8 t's, 2-3 polos, and 1-2 button down shirts. Its up to you what you bring but remember the weather is gonna be hot.
