His Hats Are Worn by Bella Hadid and Madonna

Ukrainian designer Ruslan Baginskiy is a luxury hatmaker for today’s “It” girls and Instagram stars, best known for his hard-brimmed baker boy caps in wool felts, nubby tweeds and other handcrafted materials. If John Boyd (Princess Diana’s famed milliner) had needed a social media savvy protégée, Mr. Baginskiy, who started working on his hats in college, would have been an ideal candidate.
