White Members Only jacket size 40 or woman's size 12. (I wear a 10 or 10 petite or women's M on top, and you can see in image #1 that the jacket is nice and roomy, with room for a heavy sweater underneath. But you can see that the sleeves are too long for a petite.)
Members Only jackets have a justified reputation for looking smart on both men and women.
This vintage 80s jacket was lightly used and belonged to an older lady who loved it and looked great in it. I bleached it and it is bright and clean. There are no underarm or interior or back stains. It looks as good as new.
