The Perfect Dressy Trenchcoat
Bertha González Nieves
Cofounder/CEO, Casa Dragones Tequila, 41

Why it's new: The classic trench gets a luxurious upgrade in buttery suede and leather. Not just for chilly workdays and Saturday brunches like its cotton and wool cousins, this coat is great for big nights out, too.

How she wears it: González Nieves, a New York City–based businesswoman who created Casa Dragones, a high-end tequila served in restaurants like New York's Le Bernardin and Beverly Hills' Spago, brings just one coat when she travels. "I prefer not to check bags, so I pack efficiently," she says. For a new take on evening wear, she pairs a trench with a sparkly minidress.

Why you should try it: Because a trench provides a refreshing counterpoint to all-out glamour at night. "I want to seem elegant yet approachable," González Nieves says. "A trench just makes an evening dress look so much cooler."

Adam's Tip: Pop the collar and push up the sleeves. "Think Catherine Deneuve in The Umbrellas of Cherbourg. That quintessential Frenchwoman with her one, perfect trench that she wears all her life."
