St John’s Collection black blazer w gold/blk buttons

Dare I call this vintage? In 2011 I took a job as a fundraiser where I traveled a lot and called on wealthy folks. I packed one black suit because I traveled light. My Mom (who sold couture clothing) thought that I needed a suit jacket that the women I talked to would KNOW was very pricey. LOL so she forced me to accept this one as a gift. I am retired now and Mom passed on, so time for someone else to wear it. the fabric tag was cut off, some sort of woven, stretchy, packs-well synthetic material. It’s quite gorgeous.
