This is a beautiful vest. I’m 5’9” 170 small bust, I usually wear a USA large or 12 but I went up a size because these tend to be small but this vest is actually pretty true to size, The XL fits me oversized, exactly what I wanted because I’ll be wearing this over other tops mostly, so I wanted a little more room, but I think the large would have fit just fine, it is much roomier then their turtleneck long sleeve sweater which ran quite small. I’m a huge fan of vests, it’s easy to wear, keeps yoSee full review
