pzuraqI would assume at the belt line. That's how I've always seen it measured.
For what it's worth, I found these to be very true-to-size. I just took my normal size and have had no problems.
IanAndersonI have to disagree here; I ordered a 29 (I can fit 29s and most 30s just fine) in the last drop and it doesn't even come close to fitting me. I'm not even sure that a 30 would fit honestly.
So I guess I'm stuck with $120 denim that won't fit me, no matter what I do?
kazamaSame. I ordered some 31's in the last drop and they fit great at first, just a hair loose. I ordered them a little big because I figured they would shrink an inch or so but nope. The jeans shrunk about 2 inches and are now way too tight to wear comfortably.
juscallmemickeyMassdrop ended up taking a return, so they're no longer available, sorry.
The weight is probably in the description of the drop or on RPMWEST's site, I don't think that was divulged anywhere on the product or in the documentation I received.
