Yes, some of the big manufacturers do. Polymorphe and Libidex are two I can name off the top of my head. From a business stand point I understand there is a market and they need to sell product to stay open. As a shit lord I want them to charge fatties 3 and 4 times as much, "Oh you like that top? 275. Oh yes it is 110, if you're a large or under. Exceptions are made for extra large, but those are case by case."
