Maybe it’s the dandy in me but I could easily spend all my money – and then some – shopping my way across London. (Is there another city in the world that takes its waistcoats and collar stays half as seriously? I think not.) Luckily the concierge at The Langham didn’t put me on to Trunk Clothiers, a recently-opened menswear store in Marylebone, until I was halfway out the door for Heathrow. Swedish-born Mats Klingberg is behind the impeccably curated boutique at 8 Chiltern Street where only a few of the handmade modern classics are well-known labels, with highlights including Japanese label Tabio and Porter, Boglioli jackets and suits, Edwin jeans and very appealing flat caps from Wigéns. They say good things come to those who wait. Good thing I’ve got a plane to catch.
