PEI Pastel Tie-Dye Sweatshirt

Got this sweatshirt on vacation. I asked the cashier to take the tag off because I thought I wanted to wear it the next day. But it wasn’t the right size for me so I never get to wear this. This is brand new, never been washed. However while I was taking photos, I noticed a spot in the bottom that shows some imperfection. I am not sure what it is though. It is not noticeable.
