I don't know what they use for their models but they are HUGE. I have a 32" waist and ordered my normal size. The waist is a little big, but not the main issue. The real oversize element is the extra fabric and length of these shorts, starting from the waistband. I think even if i ordered a small it would be so much extra fabric.maybe very small?definitely down a size and a size or two.I spent money on them and regret it.
