PRPS Black jeans, sz 31 (tag says 32 see description). Has waxy/waterproof feel

PRPS Black jeans, sz 31 (tag says 32). Has waxy/waterproof feel that’s really cool. I love these jeans. I’m so pissed. I bought them and they are a little tight on me. I’m a 32. All my 32s that fit measure 16-17 across. Laying down measuring across the back this measures 15 1/2”. In seam is around 32 1/2”. Button fly. Awesome cut, style, fabric and colors. Has a waxy / waterproof feel to them. Just a little too tight on me. Please measure a pair of your jeans to check. The fronts usually dip down. So I measured straight across the back. If your other jeans measure 15” -15 1/2” across these will be perfect for you and I’m sure you will love them. I really wish they fit me better. Almost makes me want to lose a few pounds just to fit in these. I’m definitely going to lose money on this one. Any questions just ask. Thank you for looking!
