You ordered 2 of these leggings, one in Black one in Gray. If you're concerned about the quality, then the same thing would have happened to the other pair as well.
This isn't your only order with us, so we would imagine you're familiar with our products enough to know that we truly do put our heart and soul into our designs. However, that doesn't mean that we always get it 100% right.
If something was wrong with these leggings, please let us know and we can replace them. They do have to have their tags attached and we must receive them within 30 days from the day you ordered. But other than that, we'd be MORE than happy to get you a new pair.
