Purchased in a size M. I am a short (4ft 11), size 12-14 woman with a large bust (36 FF) and the size M crop vest is nice slightly loose fit on me. It’s not too baggy, so I don’t look like a tent but it’s not tight, so it doesn’t show all my rolls-exactly what I want when I workout. The material is nice and cooling on the skin during exercise and I feel  both comfortable and cute! I am glad I bought it in multiple colours and would definitely repurchase.
