Plain Cotton Stiff Wing Carlton Day Collar in WhiteThe Carlton collar, probably designed as a nod to the nearby Carlton Club, was also seen in action on the necks of the iconic Bentley Boys during their heady days at the Carlton Hotel in Cannes. Sir Tim Birkin bought his trademark scarves from Budd, so it stands to reason that he stocked up on collars too! No doubt the playboy pinups of the 1920's would have had quite an effect on the shop. We recommend buying your collar a shirt size larger.
