raw mij jean sizing seems pretty inconsistent recently. I picked up a pair of 17.5cm from the soho store recently and the first pair of sz 28 i tried were really loose. The SA said there were no 27's in stock so gave me another pair of 17.5's...and they fit a whole inch tighter. He was just as baffled as I was. The size 28 raw mij 19cm i tried were Much tighter than the tighter pair of 17.5's that i left with. (for reference im a very snug 28 in petit standards).
