Reposhing this 100% linen blazer that I received today from @sbtroy. Love it as it's a bright cheery color and feels new but it fits like a size 10 and not a size 12. Hence, I am labeling it as such. I have an almost identical jacket in different color and the shoulder measurements differ. Although it measures 19" armpit to armpit (38" chest circumference), from the shoulder to the armpit measures 9-1/2" and the arm width at the armpit measure 6-1/2" (13" circumference). A size 12 should have 1" more for both measurements. Other measurements: Sleeve length: 18-1/1" Length (from armpit to hem): 15" Cotton lining. This would look fantastic over a t-shirt, tank top or shell sweater to jeans, white pants or shorts or over a dress on a cool night. I'd love to keep it but it's not a size 12 despite what the label says. I am happy to provide any additional information that may be useful to your purchase decision. Questions? Leave a comment below!
