Trina Turk 'Banana Leaf' One-Piece Swimsuit .
Trina Turk Plunge One Piece is a close second. The candy colors will complement your tan, and it's very resort appropriate.
Trina Turk 'Painted Plaid' One-Piece has cut-out sides that will create the look of a smaller waist. But this does not preclude you from doing your crunches. (Isn't this the VS model?)
Trina Turk 'Santorini' One Piece Swimsuit may boast a demure front, but the high-cut sides make up for its overall sexiness. Trina Turk sure does the female form some justice in these suits.
