This is a classic fit, vintage wash, stretch, cotton jacket. It is what I would call a fitted jacket as opposed to a loose boyfriend jacket, and looks best over dresses and with skirts as it fits into the waist rather than longer onto the hips. It also works well in Autumn/Winter as you could wear it under a longer jacket or coat.
70% cotton 25% polyester 5% elastin
I’m a Sz10 and wearing the Small. It fits me just how I like it. Not too big, and with a gap down the middle. I found it true to size. It has a lovely level of stretch and feels great on.
