Swimming costumes - sporty yet supportive

[Dereksmalls]

Help, I need to buy a new one this afternoon. I like plain "sports" type ones rather than the "lounging by the pool" variety but am v flat chested which can be made even more extreme without any kind of support/shaping.

Does anyone have any suggestion?

Thanks!

How about Next, they usually do a selection of sporty ones.
