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.
71% cotton 27% polyester 2% elastin
I’m a Sz10, 34C, 5'6" and wearing the Medium.
I found this jacket true to size and if anything a little on the neat side. It has a lovely level of stretch and feels great on. If you are bigger in the bust or between sizes I would definitely size up.
