OUR STORY
Born from a closet full of clothes and nothing to wear.
DuetteNYC was founded in 2019 by Diane Petan and Leslie Byron with one shared belief: a smaller, smarter wardrobe can make a busy life feel easier.
We set out to create the pieces women reach for first - beautifully tailored pants, refined tops, and versatile layers that move from work to travel to evenings out without missing a beat.
Inspired by the practicality and energy of New York, every piece is designed to earn its place in your closet and work with what you already own.
