Just in time for bikini season (and the latest crop from Victoria's Secret swim), supermodel Alessandra Ambrosio gave us some pointers on how to look and feel your sexiest at the beach. "Find a swimsuit where you can mix and match the bottom and top sizes to get a perfect fit," advises Ambrosio (check out the Bikini Mixer video of her fellow VS model Miranda Kerr, doing just that). "Always apply self-tanner before hitting the beach to give you a bit of color and glow without any negative effects," says Ambrosio, who uses Victoria's Secret Beach Sexy Sunkissed Bronze. "Keep your makeup natural with sun-kissed cheeks and a swipe of lip gloss—it's all you need. I also like to put some leave-in conditioner when I'm out in the sun, but most importantly have fun! It's all about enjoying yourself." Click on to see Alessandra's top five bikini picks for the season.
