I've noticed a difference in denim quality as well; my Sardinias look like the knees are JUST about to punch through and I got pregnant about 5 seconds after I got them so I've actually worn them very little even though I have had them for awhile. I even contacted Paige about this, explaining that I bought them like 2 weeks before I got pregnant and then wore them for a few months after birth and they looked like they were already about to bite the dust. They basically said, too bad, you ordered them a long time ago, nothing we can do.
But I've found Paige customer service in general to be pretty terrible, actually. Whenever I call with questions about stuff they never seem to know or put any effort into finding out. But man I want that new Wilder wash and Fir Green wash!!!
