★★★★★The fit was flattering right away and I did not have to keep adjusting it. I paired it with simple sandals and felt completely put together.

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.
This week I've now spent exactly half my life on this street. So for one week, everything is half off — and a little extra when you take more than one home:
10% extra on 2 · 15% extra on 3 · 20% extra on 4+
Your extra discount is applied automatically at checkout.
These are the pieces New York keeps coming back for. I won't be restocking them at this price. Once they're gone, they're gone.

Robert J.
★★★★★The fit is clean and comfortable, and the fabric feels breathable. It worked just as well for dinner as it did for a casual afternoon.
Susan T.
★★★★★I was unsure about ordering online, but this exceeded my expectations. The fabric feels lovely and the shape is forgiving without looking oversized.
David S.
★★★★★Exactly the kind of easy shirt I wanted. It looks sharp with linen trousers and stayed comfortable all day.
Deborah K.
★★★★★The color is even prettier in person. It moves beautifully, feels light, and was comfortable enough to wear from lunch through the evening.
Michael D.
★★★★★Simple, well fitting, and easy to style. I have already worn it twice and know it will be in regular rotation.
Michelle R.
★★★★★I wore this to dinner on vacation and felt comfortable the entire evening. It looks polished in photos, but never felt stiff or fussy.
Karen B.
★★★★★This has already become one of those pieces I reach for when I want to look polished without overthinking my outfit.
Patricia L.
★★★★★Comfortable, flattering, and easy to dress up or down. I wore it for several hours and still felt great by the end of the day.
Cynthia A.
★★★★★The print is beautiful and the fit feels relaxed in all the right places. I received two compliments the first time I wore it.
Nancy W.
★★★★★It feels feminine without being too dressy. The fabric falls nicely and the details make it look much more expensive than it was.
