Polish-born, New York-based Joanna Czech is the legendary esthetician behind some of the world’s most famous faces. Over a nearly four-decade career, she has tended to everyone from Anna Wintour and Jennifer Aniston to Kim Kardashian and Hailey Bieber, bringing the rigorous, holistic training she received in Poland to her cult facial treatments and eponymous skincare line. Her approach to clothes is similarly discerning: “The Row meets Magda Butrym,” as she puts it, with a particular weakness for old Céline, exceptional tailoring, and pieces that earn their place in a wardrobe.
