Reversible Jacket

Feels like 💯 cotton but there’s no tags of any kind. About 19” pit to pit so a medium? Here’s the deal-it had no buttons when passed on to me so I had to find some that I felt went with this pattern. I found these Abalone or MOP, whatever they are and thought they went with the Coral design. I sewed them onto both sides but I’m not a sewer. They look real good but don’t button like they should. Just leave it open or replace them. Extremely good used condition. Used contrasting thread on both sides. Ask questions! Quilted but not heavy
