@pechelman fwiw, I had a similar experience with the 888 14.5oz eco denim a few years back. The jeans fit will in waist and thigh, but could be a little lose around the crotch. I think it was down the fabric being less rigid, with a tendency to drape a little funny in looser areas. I decided the 888 cut perhaps didn’t quite fit my body type, but still gave the jeans plenty of love and wear. I sold them after about 2 years for a pretty good price, and actually quite miss them.
I picked up the IHDR-502 pants last year which are also an 888 cut. Due to the ridigity of the whipcord fabric, I don’t have the same loose fabric issue. Seems obvious, but it made me realise that dimensions don’t tell the whole story and that fabric plays an important role in how a pair fits.
Also, I’d actually be pretty happy with the fit you got. Looks relaxed and comfortable.
