I have a 36" waist, I bought 38" to be sure and it just fit me (last hole).  Good quality, the photo is wrong though you get the later tan color one if you order the brown belt.

I've used it for a while now and must say the quality is not as good as I thought.  The part that rubs against the buckle peeled off small parts of the top leather, exposing the inside.  It's big enough to be noticeable making the belt pretty much useless, so only got about 2 months worth of usage before I had to throw it away.
