Sellers do not post a size chart. Why? You have to order several sizes of the same name, because you don't know if you can guess the size or not. In addition, it's an extra job to ship a bunch of things, and then make refunds of the same pile. Isn't it easier to make a detailed description of the product with an indication of the size table. You make life difficult for yourself and other people, and you take up a lot of time.
