i apoligize for being too lazy too post a pic but i'm pretty sure i have the tightest holden salopets, that being the womens clasics, i am 5'6'' and my waist is 28-30'' and small fit fine but is a tiny bit long tho, but that doesn't bother me. i think holden sizing is pretty much just like normal trousers sizing. so a small mens will be 30" med-32" lrg-34", they are mostly tighter than usual but if you want some actually tight ones just get girls ones no one can tell unless you say so.
