In Camden market i found white pistol belts, for £7 (half the price of ones available online). Then i found gray!! so no dying! Gray pistol belts are hard to find. Well… I’ve never seen one.. ever! I know everybody buys white and dyes it gray. But i guess you now have the option to buy a gray one. All brand new, and they had LOTS in stock.
If you need more specific directions then let me know. hope this helps someone.
