Look Sexier in One Step

Look deliciously undone by letting a hint of lace peek out from a ladylike look. Blake Lively chose a dress with a purposely peek-a-boo effect, but you can reveal the lacy edge of a bra or camisole for a similar effect. Or, go the Katy Perry route and wear an opaque nude slip as a skirt.

Sometimes what you put on is more enticing than what you take off. Follow the lead of Sarah Jessica Parker and AnnaLynne McCord and add some sheer Swiss dot stockings to a little black dress for instant ooh-la-la.

Be a modern day sweater girl in this ultra-simple curve-revealing combo. All it took was a flawless fit to make Jennifer Aniston's simple separates look enticing, while Scarlett Johansson upped the ante by choosing an hourglass-enhancing skirt with a two-tone waist.

Add a feminine touch to your man-tailored trousers with a translucent top. Maggie Q bared her black bra while Drew Barrymore chose an eye-tricking nude underpinnings. Either way, keep the bra full-coverage to avoid turning a suggestion into a show.

Warning: you may have to stay clear of the touchy-feely types. Choose a luxe plush like Minnie Driver or a crushed velvet a la Hilary Swank for a look that will be (almost) irresistible.

A hot red dress plus crimson lipstick is unmistakably va-va-va-voom. Just don't overwhelm the shade with busy accessories-limit your add-ons to stud earrings like Angelina Jolie or an oversize cuff like Ashley Greene.
