Katherine’s a contributor at Marie Claire who covers fashion, culture, and lifestyle—from “Clueless” to Everlane to news about Lizzo. She’s been a freelancer for 11 years and has had roles with Cosmopolitan and Bustle, with bylines in Parents, Seventeen, and elsewhere. She lives in Boston with her husband and baby, and you can follow her on Instagram and Twitter. It’s “I go to dinner,” not “Her huge ego,” but she responds to both.
