Sézane Opens New Madison Avenue Boutique, please welcome: L’Appartement!

Published October 4, 2026

Sézane, a popular Parisian lifestyle and ready-to-wear brand, unfurled a new 2,800-square-foot boutique at 1045 Madison Avenue, joining the brand’s two New York permanent locations in NoLIta and the Williamsburg neighborhood in Brooklyn. The new location was designed in collaboration with the Saint-Germain-des Prés-based interior design studio Pierre Lacroix. This is the interior designer’s first retail project in the U.S.

There is a peculiar visual irony playing out on Manhattan’s Upper East Side right now, and if you aren’t paying attention, you might miss what it signals about the future of physical shopping. Sézane—a brand built on the digital mythos of effortless Parisian nonchalance—has just opened a 2,800-square-foot sanctuary at 1045 Madison Avenue. It joins their established outposts in NoLIta and Williamsburg, but this opening feels fundamentally different in tone.

The space, dubbed L’Appartement on Madison Avenue, blends the feeling of a Parisian home with the sensibility of a gallery, layering in books, artwork by Franco-American photographer William Klein, and vintage furniture that bring Sézane’s immersive world to life. The Madison boutique features vintage furniture, warm oak parquet floors, mirrored surfaces, sculptural lighting and a palette of chestnut, amber and ecru. In addition to Manhattan and Brooklyn, Sézane has permanent locations in San Francisco, Seattle, Washington, D.C., and Brentwood, Calif., as well as long-term pop-ups in Austin, Atlanta, Boston, Nashville, Dallas, Charleston, S.C., and San Jose, Calif.

Founded in Paris in 2013 by Morgane Sézalory, Sézane is a Parisian B Corp-certified brand. It is known for its effortless “French girl” style. The store carries women’s ready-to-wear and accessories and Petit Sézane – children’s- available in sizes newborn – 12 years.
