Perennial Favorite

"I'm attracted to very feminine clothes," says Vergara, who is appearing this month in the new 3-D film The Smurfs. This floral silk dress is perfect for an end-of-summer party, and it segues easily into fall with a chunky cardigan and high-heeled galoshes or a trench and stacked-heel boots. "These are fun outfits because they're so unexpected," Vergara says.

Velvet Revolution

Teal is about to crop up everywhere, so pairing a wardrobe staple in the saturated shade—like a pencil skirt—with a statement piece like this short velvet motorcycle jacket makes for an easy closet update. "It's a showstopping color," Vergara says, "and the jacket is not something you would see everywhere."

Hot Topping

A snappy white tuxedo jacket takes a sheer tank top and cropped pants straight through winter. With its fitted cut and leather lapels, the jacket adds polish to jeans or leggings. A lacy metal clutch, sparkling bangle and cocktail ring have a similar smartening effect. Be on the lookout for Vergara's own line of clothing, accessories and footwear, debuting at Kmart in September. "A woman wants to feel beautiful, even when she's carpooling," Vergara says. "And style should be affordable—who wants to spend $500 on shoes?"
