Philip Treacy

Milliner to royals, celebs, and fashion's elite, Irishman Philip Treacy's bespoke studio/retail shop in Belgravia has eye-catching chapeaux and fascinators at potentially trip-budget-busting prices. Treacy's couture headpieces have been a high-fashion mainstay with their avant-garde styling and painstakingly crafted materials. Pieces include sky-high, precariously perched, giant "orchids," "lobsters," and abstract arrangements of precious feathers and sculpted sinamay fiber. Although a custom Treacy hat requires deep pockets to pull off, a small ready-to-wear collection includes affordable splurges like a basic trilby or printed clutch wallet.
