Christie Brinkley and more in white-haute dresses.

These Hollywood beauties know the key to style that’s young and fresh: Brighten up with shades of white!

CHRISTIE BRINKLEY, 63

The supermodel’s secret to ageless? “I start every day by exfoliating my face.” And it’s not just her skin that radiates in this offwhite Grecianinspired design. A satin waist panel cinches her middle, a mini hem shows off gorgeous gams and a flowy cape adds fun flair.

NAOMI WATTS, 48

Shiny fabric can be unforgiving, but with the alluring neck cutouts and figure-flattering pleated skirt of her Fendi frock, the Glass Castle star has nothing to fear. A fiery lip, jeweled Judith Leiber clutch and scarlet sandals up the Old Hollywood glam.

ELLEN POMPEO, 47

The style-savvy Grey’s Anatomy star knows the simple tricks to stunning in a white shirtdress: Open the top button to let the décolletage shine, carve out curves with a slim black belt and add slenderizing length with sleek black strappies.

BROOKE SHIELDS, 52

The former model looks just as stunning in a Calvin Klein dress as she did sporting the brand’s iconic jeans more than 36 years ago! The sheath’s asymmetric draping “stretches” her silhouette and the white hue makes her bronze skin pop!

HALLE BERRY, 51

Three reasons why the Oscar winner is white-hot in Thomas Wylde: Frilly shoulder cutouts flash hints of sexy skin, a plunging neckline accentuates assets and the frayed hem lends a youthful dose of edge. Bonus points for halo-style hair hoops that add luster to her locks.

HOLLAND TAYLOR, 74

The Practice alum nails perfectly polished style! The vertical buttons on top pull the eye up and down to elongate her frame, a mermaidstyle skirt skims subtly over curves and a red-hot clutch and pointy pumps give the white frock playful bursts of color.
