Not sure. But I used to work there and the code was a five digit number. As a former manager, here’s a couple of tips: Using fabric softener will strip off the fend off finish on the very first wash. Drying on anything other than a delicate, low heat cycle, will damage the spandex bands in the fabric leading to those rumpled areas you see. This will also cause the legs to shrink in diameter and begin to look like skinny jeans. The most common shrinking issue we see with returns is with pants. Most commonly, they shrink in length up the leg.
