Dressy Blouse

Zac and Rachel white dress blouse - never been worn, and has been hanging up in my closet for at least two years. I can only assume all the yellow looking stains is just natural discoloration because I've never worn this, and it seems to match up to the wrinkles in the clothing (sleeve). I haven't tried getting them removed because I honestly just would like this gone. No stretch, probably better for a smaller XL. smoke free, pet free home
