When i first tried this shirt on, i loved it, especially because it was long. But after working out at the gym, it turned my arms, armpits and shoulders black. It took me basically scrubbing a layer of skin off my arms to get it off. I should mention I did wash it before wearing it, as I have learned the hard way with blue jeans. I wish I could take it back because this is ridiculous. For the money your spending, go somewhere else.
