Don’t toss your best daytime dress for a sexy little number at night – just transform it!

“Extra” hit the hip Beverly Hills boutique Harmony Lane, where stylist to the stars Jessie Ross showed us how you can go from day to night with just one dress.

“Don’t be afraid to mix it up,” insists Jessie, who says you can add things like a metallic shawl, a high-waist belt, heels, a clutch purse and bracelets to instantly dramatize your look!

Stars like Paris Hilton and Eva Mendes come into Harmony Lane to snatch up the colorful “Teabags” dresses, which you can glam up with a simple clutch, a pair of earrings and some heels.

The dresses cost around $200.

To sex up your casual dress, lose those popular leggings and trade them for a silk shrug, gold necklace and heels!

Of course, one of the easiest ways to go glam is to wear the ever-glamorous pearl necklace.

Just add some pearls to your outfit, lose the satchel for a clutch and complete the look with some strappy shoes.
