And the site of Charles Tyrwhitt`s first store, naturally. On the corner with Duke of York Street, opposite St James` church, is 100 Jermyn Street. It remains our flagship store to this day, a place we couldn`t be prouder of.If you`ve ever taken a trip to Piccadilly, you may well know Jermyn Street – a busy, quintessentially English place packed with the most charming Georgian and Victorian architecture. You`ll see luxury shops, cafes, and, famously, an array of the finest shirtmakers London has to offer.
