LULULEMON long sleeve pink/grey Swiftly Tech Top Sz 6

This was my daughter‘s. I remember buying it and it was a size 6, but she removes the tag from everything. But I was looking up the dashes on the inside bottom and the thing I googled said that three dashes is a size 8, but I really remember this being a size 6. Any way, see the last picture. I noticed a small grey possible stain when I was packaging it. Not noticeable at all, but I had to show it. Otherwise, perfect condition.
