Thach No. 1

Thach No. 1 is our first designed collection — a study in American classics, reimagined through the lens of Thach. Designed and hand-sewn in New York by our founder Anna, each piece carries the spirit of our bayside home on Cape Cod while becoming distinctly our own.

The Last Light Mini mirrors the shimmer of the sea’s remnants, its hand-beaded fabric reflecting what’s left along the shore. The Thach Catch Tank reworks the essential white tank with delicate fish at the neckline. The Slip Cami offers a sleek second skin with a silver fish detail, while the Bay Shorts are made for living — lounging, layering, and everything in between.

This is where our design story begins: timeless silhouettes with the ease of our heritage, made distinctly Thach.
