So I ordered a pair of the selvage skinny rigid rinse online, got them today and tried them on. Tight in the thighs, so I did a few lunges to stretch them out. Lo and behold, the seam near the knee is coming apart. I think because the demin is quite thin, along with the stiff rigid rinse is the cause. What should I do? Exchange for a new pair, or maybe wash them to soften up the fabric and close up the seam via shrinkage (although I don't want to wash them yet)? Upon inspection of my other leg, the same thing is happening. And if I try to pull gently apart this seam in other parts, it does come apart relatively easy. Anyone else have this problem? Thanks.
