I had originally purchased these in a large, following the sizing guide, but found them way too big around the waist. Exchanged for a medium and the fit is better. Still, I find the waist too loose and the pants slip down a bit as a result. Not sure if continued sizing down to a small would help as I have a small waist but larger hips. Not the best fit for me but the pattern, material, and workmanship are amazing.
