Outfits That Walk Between 2 Worlds

A mainstay on the city’s charity circuit, Muffie Potter Aston was formerly the United States executive vice president of marketing and advertising for Van Cleef & Arpels. A Washington, D.C., native, she lives on the Upper East Side with her husband, the plastic surgeon Dr. Sherrell Aston, and their twin 6-year-old daughters, Ashleigh and Bracie. BEE-SHYUAN CHANGWEDNESDAY, NOV. 2

The gym is my shrink each morning. After I’ve gotten my girls ready for school — thank God they wear a uniform, so there is no morning quandary as to what they should wear — I put on my gym uniform: One Step Up boot-cut exercise leggings and a T-shirt usually from a charity benefit gift bag. Today’s tee was from Trudie Styler and Sting’s annual Rainforest Foundation benefit.

I met Adrienne Vittadini for lunch at Swifty’s. The weather was gorgeous, and I went with Hermès: a black suede fitted jacket with long fringe and nutmeg-colored calf-leather pants. Paired that with Manolo Blahnik ostrich booties and my black Birkin.

Then a trip downtown for a meeting to plan next year’sRita Hayworth Gala. Back uptown, picked up my daughters at school and changed into my “play clothes” to hang with them: a long-sleeved white Gap tee, khaki Gap pants and a cozy mustard Tse V-neck sweater.

Another morning of school drop-off in my gym uniform. This tee was one from the New York Jets commemorative 9/11 opening-night game. Later, I had annual appeal solicitations — when board members sit down and write fund-raising letters — to do for the Memorial Sloan-Kettering Cancer Center. I wore a camel cashmere Chanel jacket, gray flannel Michael Kors trousers, blush Saks Fifth Avenue Private Label turtleneck and a blush and gray paisley Loro Piana scarf with black suede Chanel loafers. And I carried my burgundy Birkin.

After dinner with my family, it was off to the Marine Corps Ball for cocktails and then to Broadway to catch “Spider-Man” with a couple of girlfriends. This was tricky wardrobe territory as the ball was black tie and the theater obviously not. So I went with a Yves Saint Laurent black velvet tuxedo suit, white satin Naeem Khan blouse and Badgley Mischka’s rhinestone and black velvet belt with black suede YSL pumps. En route to the theater, I took off the jacket and the belt in the car and threw on a cashmere Pucci print V-neck.
