This 100% cotton shell jacket has a warm polyester shearling like lining and is fitted - size 10 (here in USA) but I found arms to be slim fitted - shown on small bust for reference - huge oversized pockets - could use a treatment but afraid to wash or dry it - may need to be redipped by Barbour with waterproof wax but could also be worn as is - measures 20" across chest pit to pit when zipped and buttoned - 30" long top shoulder to bottom along front - sleeve is 22" seam to end - approx 18" (like 17 3/4")across top back shoulders seam to seam - these are outer dimensions so keep in mind it is lined and padded will be slimmer - size is 14 in UK
