Pink women’s jumpsuit size 4

From a smoke-free home. worn only once last year for a Halloween Barbie costume. there is some slight staining on the left leg. I purchased this off of eBay new w tags but it arrived w this stain. I did not realize it until after I had already removed the tags. Can’t really notice it when you’re wearing it so I didn’t care. I’d keep it, but I actually need a size larger. Selling at a discount due to this. Could easily alter to make shorts jumpsuit to remove the stained area.
