What should I bring?

This summer, I'm going on a two week trip to Martha's Vineyard. Sure, we go every year but this year I want to look my best! We have a washing machine so there's no need to worry about that. I'm 13 and am 4'9, have a 32A bra size, and weigh 93 pounds... I don't know why I put that. I don't really shop at Hollister or Abercrombie. I only shop at Hollister for their tanks so please don't recommend those stores unless it's for Hollister's tanks! So just like a list such as "2 bathing suits, 3 pairs of flip flops, ect." Thanks!
