Chic Office Dress Code

Every woman should have: A gray men's crewneck sweater from J.Crew. It travels with me to snowy — and sunny — destinations. It mixes well with any outfit, day or night.

Three rules to dress by: 1) Don't match — mix prints and colors. 2) Don't wear skirts too short — if you're unsure, wear them with flats. 3) Don't try too hard — or at least look like you didn't.

Style Note: "Wear a pair of socks with strappy sandals to make a color statement, but never match them to your shoes."

Skirt price upon request, Matthew Williamson. Shoes $940, Giambattista Valli. All other clothing and accessories Joos' own.

What I do: I head the accessories team at Ann Taylor. We work on everything from jewelry and bags to shoes, belts, and scarves. It involves a lot of sketching and even more traveling for inspiration.

What I wear: My look varies with my mood, but I always fall back on a feminine dress with a jacket and killer heels.

Necklace $58, ring $48, bag $298, Ann Taylor. All other clothing and accessories Tapia's own.

Every woman should have: An Alexander Wang leather jacket. I wear mine with literally everything.

Three rules to dress by: 1) It's always better to be overdressed than underdressed. 2) Don't take yourself, or your outfits, too seriously. Walk your dog in a gown, or go to a gallery opening in pajamas — just wear something fabulous, like a great necklace or fur gilet, with them. 3) Don't overdo it. Never wear designer or fast-fashion head-to-toe or aim to be perfectly polished.

Style Note: "Balance is key. If you're wearing jeans, wear statement jewelry. If you're in a cocktail dress, go with minimal makeup and messy hair."
