Alessandra Ambrosio

The “Angel” posed for Victoria’s Secret in a patterned bikini on the beaches of St. Barts.

The actress picked a mis-matched suit (with the shoulder straps pulled down to prevent tan lines) while in Cabo on a birthday trip with friends Courteney Cox, David Arquette and then-rumored-beau Gerard Butler.

Brooklyn Decker

The Sports Illustrated Swimsuit Issue cover girl wore yellow while filming the flick Just Go With It in Hawaii.

Best Bright: AnnaLynne McCord

In Miami, the 90210 star opted for a hot pink two-piece paired with multiple bracelets, necklaces, and simple black shades. The vibrant color was perfect for the setting—and brought out her (safe, we hope!) tan.

Kristin Cavallari

The Hills star wore a simple black string bikini—with bangles—at a party in Las Vegas.

Kourtney Kardashian

Another sexy Kardashian sister, another metallic suit!
