As far as it fits, it can't fit. Tighten it until your pants stay in place. The size chart will work - or you can tie the ponytail around and down in medieval fashion. The blue color might put you off wearing it regularly, but I bought it for my cargo shorts and no one complains when I wear it with faded jeans. Because it's synthetic, it won't discolor when wet. At the same time, I wouldn't carry anything heavier than a cell phone with me, so don't throw away your fanny pack or tool belt just yet. My dad got one (in a different color) for my mom when she was starting to wear out. So if you're a tall man with a lot of EDC, this might not be your chance to go without suspenders. mine is holding up well.
