Mickey Mouse unlimited vest vintage Circa 1990's. It is marked one size fits most

I would say buttoned it would be a medium to a large but can be worn unbuttoned. There are lots of photos with measurements. The tag states Dry clean only. (it was gently handwashed with no problem)

100% Polyester

Pictures taken with measurements. It very good condition from a personal collection. Time for a new home. A quality piece that will last for years when cared for.
