I just bought this dress last Friday to wear on New Years Eve. It's stunnnninngg!! So comfortable, fits beautifully, very flattering. HOWEVER I wore it and it stained my arm pits BLACK. Like horribly, and it did not wash off right away or easily. I'm hoping after giving the dress a few washes any excess dye will be gone and it will no longer happen. So love it, but just felt the need to warn others about the side effect.
