I purchased this new at a store last year. I've only worn it once each for a half marathon and a full marathon. The reason I'm selling it is because my legs gave out during last year's full marathon, and I was cold. There are some marks left from the race bib, but I don't think they'll be very noticeable if you smooth out the wrinkles. *It's the type that snaps on, not the kind with safety pins. There are no holes, so please don't worry about that. The size is XS, but it's a Western size, so it's a Japanese S size. The seller is 166cm tall and weighs 63kg, and it fit perfectly. The color is dark purple. #running #jogging #singlet #saysky #runningwear
