About onsēm

onsēm was born in 2021 from a love of prints, a sewing machine, and a deep appreciation for slow fashion. 
What started as a simple skirt made from leftover pillowcase fabric grew into something much bigger — a celebration of modern design, vibrant African wax prints, and the stories they tell.

Originally founded by three French women  - Charlotte, Marie and me, Frédérique who met in New York -  onsēm has since evolved into a solo journey.

Every item is made in small batches in collaboration with ethical, family-run workshops in New York’s Garment District and Brooklyn. 

It is a labor of love, rooted in slow fashion, sustainability, and craftsmanship.

At onsēm, it’s not just about clothing — it’s about embracing the colors, textures, and stories that shape who we are.

Designed to move with you from day to night, each piece is made to feel effortless, elegant, and uniquely yours.
