What bikini fits my body best?

I'm 16 (so please no barely there bikini suggestions) and am 5ft2. I'm looking for a bikini that might make my legs look longer? But, my boobs are a bit...ehh. I wear a B cup, but they are closer to the just out of A size, if that makes any sense at all? I'm not itty bitty teen skinny, but I'm thin. Also, are there any colors that would help absorb sun more? I'm kinda fair toned and looking to bring in some sun this summer, with sunscreen of course. Thanks!
