Don’t Call These Clothes Minimalist. Or Quiet Luxury for That Matter.

“Quiet luxury, oh God,” Isabel Wilkinson Schor, the designer of Attersee, said with a small sigh. “I don’t consider us a part of that trend at all. It’s been around for a very long time, and it’s equated with minimalism. I don’t see what we are doing as minimalism.”

Attersee, which Ms. Wilkinson Schor founded in 2021, is known for the kinds of high quality, strokeable fabrics associated with the trend. The clothes are classic in that they are not meant to easily go out of style, but do have quirks: a knit tube wrap as an alternative to a cardigan, a print of figure drawings, a plissé silk cape dress and caftans for summer and winter.

The impetus for the line was simply to find everyday clothes that were comfortable and beautiful, not the kind of thing that would be worn only to a big event once a year. There are oversize collarless shirts in a silk-cashmere blend for $525, sculpted duchesse satin vests for $725 and linen-cotton Mary Janes made in collaboration with the Italian shoemaker Drogheria Crivellini for $175.

This week Attersee, which is named after an Austrian lake where the artist Gustav Klimt spent summers, is opening its first public showroom, in a former fitness studio on the Upper East Side. It is a working space for Ms. Wilkinson Schor and her employees as well as an appointment-only place for customers to see and try on the clothes in person.

Ms. Wilkinson Schor, the former digital director of T magazine, grew up on East 19th Street in Manhattan, eating at Veselka and shopping at Love Saves the Day. Until she moved to the Upper East Side in 2020, she had lived downtown for her entire life.
