Who says you can’t afford anything from a Savile Row tailor. The much admired tailor Norton & Sons have recently released their Trotters Bag. Per the company website. “The Trotter, the most junior rank on Savile Row, trots between cutting rooms and workrooms, carrying bundles of cloth and trimmings to the sewing tailors and returning with sewn garments. At Norton & Sons our trotters use a traditional stout canvas Trotters Bag.”
I don’t think it gets more insider than to own one of these bags, although I would much prefer to show my rank with a Norton & Sons suit.
