Formal Vest - Black

I purchased this new and wore it once or twice. It has been stored in my closet at home since then.
The purchase date and location are unknown.
There is no size listed, but I usually wear a size L, so I've listed it as L.
There are two decorative rows of pockets at the top. It's black, so dust is noticeable, but there are no particular stains. I hope someone who understands this will purchase it. (*^^*)
