I purchased this at Marui and have been using it with love, but I'm selling it because the size no longer fits. The Marui size is listed as 6L, but based on how I wore it, I think it would fit someone who wears a size 17 in Onward brands like 23区 or ICB. If you prefer a looser fit, it might fit a size 15, and if you like a tighter fit, a size 19 might even work. The color is navy, so it's easy to match with anything. It comes with a belt made of the same fabric.
