Zara Pink Sweatshirt and Legging Set

This cute set is adorable and has been worn a handful of times. There is a small stain on the sweatshirt as seen in pictures, as well as a small pink stain on the left leg of the leggings. I have not treated either stain, so they may be able to come out. I also noticed slight discoloration on the knees, which may also be able to come out as I have not treated that area either.
