@yannis ah cool, ya, I've had that issue with other jeans. Sizing up often just means that the waist ends up being way too big once everything has loosened up. As long as the 634 isn't secretly a slim fit, the same size should be right.

ya, the shop gave me the same advice, either same size or size up should be good. My 888s are great in the waist but kinda a bit tight in the thigh, but that could be due to the taper to the knee. Lifting weights has made it a bit of a challenge to get jeans to fit in both the thigh and the waist, usually I have to pick one or the other.

I've got a pair of 888-21s in 34 and was thinking about picking up a pair of 634 for that straight legged vibe. Any advice on what size to get in comparison with the 888? My only concern is the thigh measurement because I don't really want the hips any tighter than the 888s are. Anyone have any experience buying both?
