Black vintage cotton pleated tank top 10 m

Black pleated in the front to show curves. White around the trim, shown in pictures. There are six buttons in the back for closure also pleaded in the back shown in picture for curves. The tag says size 10. I believe this fits more like a medium. I am going to post this as a size medium. I am 5’2 or 5’3.. and that’s what it looks like in the picture of me wearing this blouse. I do have a long torso if that helps. (No stains, pet and smoke free home)
