We bought a 3-pack of City Threads and loved them so I decided to buy another pack, but went up a size so my son would be able to wear them longer. When they arrived, I decided to keep them aside since they looked quite a bit larger (but true to a size 7 I think). He's worn each pair about 10 times or so since I've opened the package and rotated them with his other undies. For some reason, on one pair the seam at the top (where the stomach area is) has about 6 places where the stitching is coming undone. This is way too soon for this to be happening, so clearly there is a workmanship/quality issue. Other than that, we love the product- they are super comfy, soft and fit nicely. I like the snug fit as opposed to looser underwear that gets baggy in the leg holes and lets too much show. For the price, this should not be happening.
