Are you hitting the beach this Fourth of July? Take a cue from Cameron Diaz and slip into a teeny bikini. "I love surfing in Pualani Hawai'i bikinis," Diaz told InStyle. "They're tiny, so you get a really good tan, but they stay on." As for footwear? "Always Havaianas. Preferably in white." Pick up Pualani Hawai'i's $69 triangle top and $69 bikini bottom at pualanihawaii.com, and shop Diaz's flip-flops for $18 at havaianas.com.
Plus, shop more star bikinis!
