You don't have to have stellar genes and VIP access to the most smokin' swimwear to look as sexy as a Victoria's Secret model this summer. We asked "angels" Alessandra Ambrosio and Miranda Kerr for their best beauty and body-confidence secrets. Use their down-to-earth tips to feel like a bombshell at the beach.

Pick a suit you feel comfortable in

When it comes to finding the perfect swimsuit, it's more about comfort than trends. No one knows this better than Brazilian-born Alessandra. "In my country, swimsuits are practically a national uniform," she says. "It doesn't matter what you wear, it's how you wear it."

Pick a style you can rock with confidence. And if you're one size on top and another on the bottom-like most women-pick a store where they sell separates. "One of the hottest swimsuit styles of the season is a halter top, which gives you a little lift up top. But go for what you like or you'll never feel sexy," Alessandra says.

Fit in exercise whenever you can

An athlete all her life-growing up in Australia, she played basketball and did gymnastics-Miranda has always been active. "I don't do it so much for what's on the outside as for what's on the inside. I just know that when I exercise, I'm more energized and productive." Although she hasn't had time for team sports in a while ("I have literally worked six days a week, barring Christmas, for months," she says), she squeezes in at least a bit of yoga every day. "Sometimes you'll even find me doing down dog or sun salutations between shots!"

Indulge in moderation

Even supermodels splurge-but in moderation. "I'd say I'm 80 percent organic and 20 percent indulgent," admits Miranda. She loves juicing (blending spinach, carrots, beets, and ginger) and indulges in a good steak when she's feeling run down.

Try this to nix puffiness

What about those days when the last thing you want to do is slip on a suit? When Alessandra feels puffy, her strategy is to avoid carbs and load up on fruit, salad, lean meat (like chicken), and tons of water. Her secret weapon: fresh watermelon juice.

Let your mind take the lead

When it comes to body confidence, Miranda is a big proponent of mind over matter. "Sure, it's easy for me to say that as a model, but whoever you are, you can choose to focus on your best assets," says Miranda. "Embrace what you've got. Acceptance gives off good energy, and there isn't a person alive who isn't attracted to that. A fabulous suit and a touch of self-tanner don't hurt either!"
