This is the inner vest that came with the coat. It has buttons on both sides and the back of the neck to secure it to the coat. I always take it off and wear the coat, so I don't use it much... It has been dry cleaned. It's a size S, but I usually wear a size M. I will fold it as small as possible and compress it for shipping. m(__)m Color...Navy系 (Navy-based) No stains, tears, or odors.
