What swimwear would look good on my body?

I am going on a cruise this summer and I have to buy a suit or two. However, I am absolutely clueless about what looks good. I am 13 years old, six feet tall, have broad shoulders and hips, and the rest of me is gangly, thin and pale (yes, I stand out quite a bit). Can anyone direct me to some suit styles, brands, anything? Thank you very much! :D
