I have a 31" waist but bought a size 28 belt based on this company's sizing chart. I received the wrong size, 26, in the mail and it didn't even reach the buckle when wrapped around my waist. Size 26 should be at least the loosest size according to the size chart in the pictures. So I sent it back for what I ordered, 28.28 arrived and won't make it to the first hole. According to their size chart, it should have a "medium fit". It won't even bend if I suck in my stomach and pull with all my might. Of course I will return this product and buy from another brand. If the company creates an odd independent sizing guide, that's fine. But that is completely wrong.
