This is the only issue I have with Gustin jeans. Anyone know why certain pairs sew up small? Is it the person cutting the patterns or maybe the material itself?
I had to return a pair that were sewn up way small. The rise was an inch short of the chart and that's not a little bit. I could button them but it looked like I was wearing some low rise joints. I have another pair in the same size that are my best fitting jeans ever. Gustin cust. serv. is great though, they took care of me. If pairs were consistent to sizing, I'd probably have a closet full of their denim.
The fabrics are one of the main drivers of this. I'm not entirely sure why but that is one of the reasons that other companies tend to focus on only a handful of fabrics - they build familiarity with them and can more easily predict their sewing/shrinking/fading characteristics
