Yesterday was the first time I wore these leggings not even for 5 minutes and my hands had a black stain on it. I wasn't sure where it was coming from but as the days went on my hands were getting stained and more stained to at the point where it looked dirty. I'm not sure if I just got a bad pair or what and I had just got my nails done the previous day a light pink gel and the stain dyed my nails and turned them purple. Taking a shower and washing my hands multiple times took the dye out but other than that these leggings are very good stretchy and not see through at all.
