Miss Claire Sullivan on Modern Couture, the Glory of a One-of-a-Kind Piece, and Designing for Sarah Jessica Parker and Addison Rae

Claire Sullivan is a designer, creative consultant, and founder of the design label Miss Claire Sullivan. She grew up loving fashion and has a penchant for dramatic, voluminous designs. It’s no surprise, then, that after working as the co-creative director of the streetwear label Vaquera, she founded her own atelier, where she creates dynamic, one-of-a-kind designs. In the past year, she’s generated several iconic red carpet moments, such as Addison Rae’s padded bustier with a big tulle skirt. Her pieces have also been worn by the likes of Chappell Roan, Kylie Jenner, and Camila Cabello. This week, Sullivan joins Who What Wear Editorial Director Lauren Eggertsen to discuss her earliest style influences, what it's like to design custom pieces for her clients, and how she created an Anna Wintour–approved dress made out of maps for Hailey Bieber.
