Look Sexier in an Instant!
Undo a Button
It doesn't get any easier than this simple move: Loosen up a button-down just enough to reveal a delicate collarbone, like Elle MacPherson, or draw even more attention to your decolletage by wearing a statement necklace like Eva Mendes.
Slip on this bold, look-at-me shade, and get ready to stop traffic. Find a sheer red sheath, like Diane Kruger's, that still leaves something to the imagination, or follow Penelope Cruz's lead by going head-to-toe scarlet in tailored-but-relaxed separates.
Sport a Pencil Skirt
A single episode of Mad Men is enough to illustrate the usefulness of this sexy staple: Modern women like Kate Bosworth should try textured leather for an edgier take on the silhouette (add a soft, feminine top and pumps to make it office appropriate), or dress your skirt down, like Jessica Biel with a loose silk tank and platform sandals.
Show Some Leg
Look beyond cut-offs: Short-shorts can be surprisingly polished. Take your inspiration from Kate Walsh and wear strappy metallic sandals with a tailored (but still sexy) pair, or lengthen your legs with playful heels like Rihanna's.
Wear Skinny Ankle-Length Jeans
Anyone who's seen Grease knows that a pair of cropped skinny jeans can be the key to going from all-American sweetie to sexy siren. Gwyneth Paltrow's super-fitted light indigo pair emphasized her curves and played up her strong-shouldered blazer while Cameron Diaz's darker dungarees highlighted her sassy peep-toed sandals.
Shimmer all summer with small hits of sequins or shining beads—a little dose of sparkle is an easy way to draw some eyes. At night, go full-on glittery like Jennifer Aniston in a luminous minidress and strappy metallic heels; or tone it down for day like Alicia Keys by choosing simple separates with just a hint of shine.
Bare Your Shoulders
This summer, shapely shoulders are begging to be shown off. Turn heads in a romantic, asymmetrical dress (like Camilla Belle) or follow Ashley Greene's sexy example by baring both sides in a sexy off-the-shoulder look.
Add a Dash of Leopard
Even a hint of this distinctive animal print can pack a punch. Avoid going too wild by breaking up the pattern with solid accessories and separates like Vanessa Hudgens, or consider Kate Moss's combo: Wear a leopard-spotted shoe with a loose-fitting dress for an unexpectedly sexy look.
Throw on a Leather Jacket
Of late, the leather jacket has graduated from rebellious extra to wardrobe essential, but it still looks sassy when paired leg-baring separates. Choose a streamlined style similar to Beyonce's blazer if you want to rock the jacket with a pretty mini or opt for Blake Lively's sporty, motorcycle cut if you love the look with shorts.
