The label
From Umgee
Umgee is a U.S. boutique label loved for relaxed, feminine silhouettes — flowy tunics, puff-sleeve blouses, and easygoing dresses with a soft bohemian streak. We stock Umgee stateside and add new arrivals often. Fits run generous and forgiving; check each piece's measurements for the exact drape.
