Twenty-three years on West 23rd Street

Twenty-three years ago this September, I turned the key on a narrow shop on West 23rd Street. I was twenty-three years old, with my mother's pattern notebook under my arm and not much else.

She'd spent thirty years cutting on Seventh Avenue. She taught me one rule: a piece is only good if you reach for it on an ordinary Tuesday. That's still the only rule this store has.
