DOEN Buttercup Mini Dress in Wine Winter Ditsy In soft cotton viscose, the DÔEN Buttercup Dress is our grown-up take on a babydoll dress, with a square neck and keyhole back, and dramatic bubble sleeves with ties reminiscent of our favorite Renaissance looks. We're wearing it with thick black tights for winter warmth, and Mary Janes all year round. 52% Cotton / 48% Viscose Bust: 18" Length: 34"
