Yeah the pants sizes change with every drop, I own 3 pairs of ralphs all medium and they all fit different my rust ones(black floral lining) fit good but seem to have the less give in the material, my black ones (pin up girl lining) are fine found waste but tight as in the legs from thigh down to ankle, then my forest green pair (trout lining) fit the best slightly looser around the waist but much more relaxed through the leg most comfortable paid by far.
I tried on black ralphs from the lastest drop this weekend and this is how I know the sizes have def changed... I couldn't pull the M past my ankles so couldnt try those on so grabbed L and the where prob just as if not tighter and my more restricting then my M pairs, new ones are def shorter and the material seems to have a lot less stretch
The new iteration of the ralphs are damn restricting. It's super tapered below the knees and worst still, the leg opening is narrow. You must have skinny/slim calves or can't pull this up without "pulling" it up with some force. On the first try, it's uncomfortable, but after a few wears, the stretch starts to conform a little.
Verdict: Size up, and life would be easier. (even if the waist hangs loose by 1 inch gap.)
