Definitely size UP by 1 or 2 sizes when ordering these jeans!!! I just received my size 30 USDG 14oz denims (thinking they would be a snug fit) and I can't even button them up. UGH! There goes $100 that could've been better spent on another Spyderco or flashlight. lol (For context I'm 5'7", 135 lbs: I have three pairs of weirdguys's in size 30; a slimguy in 30; a snug-fitting skinnyguy in 31 and a loose-fitting skinnyguy in 32). I really wanted a 31 or 32 but they were all sold out when I joined this drop; I should've pulled a 'Kenny Rogers' and walked away.
StevenTboneI had the same problem. I had to upsize my normal waist by 2. and then it was a TAD loose, but the original I couldn't even get the button on.
