What would you bring?

Let's say you were going to travel to the Caribbean for an extended stay, what would you bring? I've been trying to make a running list of things that might not be readily available to me while in St. Thomas like it is in the US.
Since almost everything is imported, I've heard if you see something you like or might need to use multiple times buy more than one... it might not be there when you go back!

My list seems small and petty so far so I need some help... check it out:
-Bath and Body works lotion and shower gel
-Medicine
-Straightener (maybe I won't need this since my hair will be a frizz ball)
-Make up (I doubt they have a State beauty supply)
-Social Security card, marriage certificate, driver's license, passport, and birth certificate

I'm clearly missing some things... add your input in the comments section.

PS- I will be taking clothes don't worry, this won't become an episode of "Naked and Afraid" but I figured clothes was a "duh" thing to list.
