SUMMER and choosing swimsuits...blah...

I am completely retarded and indecisive when it comes to stuff like this and I'd like to avoid my buying and returning as much as possible!
I have been dying for the new suits at down east basics online to come out and they are finally here!!
I fell in love with the silver and white one from the catalogue but now I'm not sure!!
which one should I get? I LOVE white b/c it makes me look more tanned (lol) but I also love this turquoise one...sigh... I know this is probably lame to you but I just need some girly opinions!

keep in mind, I am NOT curvy and I have NO boobs:)
every year I HATE buying swim suits. I am completely UN proportioned .....and it makes me want to scream. I wish I knew of some good swim suits for SPORTY physiques. if you know of any, let me know! I sometimes wish I could just wear my sports bra and some boy shorts! LOL
