Amy Rosi knows how to make an entrance. Whether she’s dressed in a black form-fitting coat, with a red skirt peeking out at the bottom, black high heel ankle boots and a black fur hat, or she’s wearing her favorite vintage pieces, Amy Rosi has an innate sense of style and grace.

Like many young women, Rosi came to New York with dreams of becoming a ballet dancer and an actress. And like many women, she got sidetracked by the business of making a living. “I got a job working in public relations, and I had a talent for art, and that’s been my career path. Marketing, branding and communications.”

Since 1999, Rosi’s owned and run Aros Communications, a company that focuses on everything from business and product development to marketing, advertising, even event management. Some of Aros’s clients include Bergdorf Goodman, BMWi, Cartier, David Yurman, Daum, Escada, Hasselblad, Jane Seymour, Saks Inc. and Stephen Dweck. “I’ve never actually solicited a client,” Rosi said. “One client leads to another.”

Amy Rosi prefers the dynamics of a smaller, boutique firm. “I was at Condé Nast for years, Marketing Director for Mademoiselle. I worked for David Yurman, which we built into a very large company. Hundreds of employees. I worked for Escada, which is almost a billion dollars. As my own boss, I prefer more intimate relationships with my clients.”

Even though Rosi’s employees come to work at the office in her apartment, Rosi dresses up, every day. “My life is very day into night. I’m a more formal dresser. In a home office, a lot of people are very casual. I’m not, because I’m out, a lot. Like this morning, I had a breakfast at Plaza Athénée, and then, I’ll be out for a lunch meeting.”

Amy’s style strength comes from knowing her good points and emphasizing them with each wardrobe choice she makes. “I buy things because of my size. I don’t wear oversized clothes. I like the French idea of a little sweater or a smaller shirt.”

A tour of Rosi’s closet is a lesson in style. “I have lots of old and new pieces I add and subtract as needed. I wear a lot of vintage. A little beret, a pair of tights and some black flats, and I’m ready for the Armory Art Show.”

“I love this coat because it’s very French, very fitted, and it’s shorter than any skirt so you never get this dowdy look. I’m a very short person, so I try to lift everything up.

“My favorite pair of pants are Escada hip huggers. Very sexy pants. Instead of wearing a jacket, I’ll wear a camisole and a great fur jacket, and all of a sudden, it’s a totally different look.

“TRAVEL, WORK, LIFE… EVERYONE SHOULD HAVE AT LEAST ONE PAIR OF VELVET JEANS. ANOTHER ESSENTIAL IS BLACK JEANS AND A BLACK CASHMERE SWEATER, AND I ALWAYS WEAR A LITTLE RED.”

“I buy buttons, and I’m always reconfiguring. Here’s some I bought at a flea market,” she says, pointing to a box of vintage buttons.

“This is my favorite thing in the world. It’s knitted rabbit fur. I wear it as a hat or sometimes around my neck, and this Yves Saint Laurent scarf… It can go casually over my coat, or can become something very elegant with a cocktail dress.

“Oh, and I can’t give up my Marc Jacobs shoes!”
