Shapewear Report: Summer's Must-Have Bras

As Jessica Biel knows, halter tops and summer go hand-in-hand. Opt for a halter bra-they usually only have one adjustable strap.

Want to follow Fergie and display your sexy back? An adhesive bra offers no-show support.

A white sheath like Jennifer Aniston's calls for a seamless bra. Look for one made of foam in a shade close to your skin tone; they're excellent for creating a smooth shape that looks great under tight-fitting or light clothing.

Diane Kruger's super-sheer sheath leaves little to the imagination; try a shapewear bodysuit that matches your skintone for optimal coverage.

For ever-popular one-shoulder styles like Eva Longoria Parker's, bras with adjustable straps that can be arranged multiple ways are key. (Bonus: You can use them for strapless or halter styles as well!)

Zoe Saldana's plunging neckline calls for a bra with a deep, wide-V shape and a center band that sits lower on the rib cage.

Wear a racerback tank like Kim Kardashian's with a bra that makes an X shape between your shoulder blades.

When wearing a strapless dress like Kerry Washington, you need a strapless bra. It should have wide sidebands and no straps, but underwire is optional, depending on your support needs.
