Whether she was dressing for the area's heat advisory or just flaunting her supermodel bod, Brooklyn Decker was all smiles and all leg at a Sephora event in NYC on Tuesday.

Paying homage to the skin, hair, and makeup metropolis's black-and-white color scheme, the blonde beauty sported a thigh-grazing Alexander Wang mini dress with Valentino Studded Point-Toe Pumps. And despite the minister-inspired white collar, the plunging slit down the center upped the outfit's sex appeal.

In addition to showing some skin, the 24-year-old styled her blonde, cropped strands in a swingy blowout. So what's her secret weapon to keeping her sunny locks ever-so-sexy?

"The best hair product in the world is salt water straight from the ocean -- it's so good!" Decker told Us Weekly at the event. "It sounds gross, but when I go to the beach, I don't wash my hair for a day or two because it's so wavy and beachy."
