Fashion tip

Instant Glam-You-Ups

Put on a skinny belt.
Add shape to a shift dress, a blousy top or an oversize cardigan by adding a low-slung leather belt, like Gisele did-and you don't need her body to pull it off.

Fancy-up your pony.
Get a red carpet one a la Eva Mendes's by teasing the front to add a bit of pouf and taming flyaways. Try Samy's Samysmooth Laminating Hair Polish.

One word: hoops!
It's impossible not to look glam with them on. Jennifer Lopez went for triple-threat hoops, but any big, silvery kind will do. Just keep the makeup simple.

Do un-shy lips.
A classic, starlet-red lipstick: The glammest of 'em all. Jessica Alba's shade looks pretty on all skin tones; try Revlon's ColorStay Soft & Smooth Lipcolor in Red Velvet.

Play peek-a-boo.
Wear an open, fitted blazer over a flirty, low-cut cocktail dress like Thandie Newton did--the perfect combo of structure and all-out sexy.

Slide on a wide headband.
It looks equally chic with boing-y curls or straight hair. Try Goody's StayPut No Slide Headbands to get Jennifer Hudson's effortless movie-star style.

Carry a colorful bag.
Spice up a neutral ensemble, as Amanda Bynes did, with a big, bright purse.

Try a chunky necklace.
Ditch the delicate jewelry for something with presence--see how this piece dresses up Mena Suvari's ordinary sundress?

Wear larger-than-life sunglasses.
A pair like Mischa Barton's (so Jackie O!) keeps the glare from the sun--or paparazzi flashes--stylishly at bay.
