Old Navy ladies sweatsuit in vintage stripe

Old Navy ladies sweatshirt and shorts in a vintage stripe of various blues and yellows. The sweatshirt is a size medium with the neckline, cuffs and hem all being a contrasting blue. The sweatshirt is a size MEDIUM. The shorts are drawstring and size LARGE. I didn’t think I had worn them but there is a small stain on the back of the shorts. I thought it was fuzz at first but it seems to be on the shorts.
