Vintage Butte Knit Vest Button Up Navy Blue with Pockets Women's Size Medium

Vintage Butte Knit Vest Button Down Navy Blue with Pockets. There is a hook and eye closure (although the eye part is missing), but the hook slips into the remaining thread knot just fine. As for the size, there is not a size listed on the tag, but based on the measurements of 18" wide across the front at armpits, it seems to be a size medium. Please compare your own clothing measurements to the ones shown before buying. BIN DD:PFM2/0806-0714
