NWOT Irvin style RAF sheepskin flight jacket, made in UK by Polden.  Tag shows size L.  I wear 42 and it's loose on me, so I would say it fits more like a 44-46.  Measurements with jacket laid flat (please make allowances for small measurement variations):

Shoulder to shoulder:  22"
Armpit to armpit:  26" (measured at middle seam of gusset)
Collar to hem:  26"
Hem:  23"
Shoulder to cuff:  25.5"

Jacket is absolutely new, smells like new, worn only for photos.  Skin is treated with some kind of coating, that's why it's shiny.  No returns, no refunds, sale is final.  I have a collection of B3 and RAF jackets, some of which I have never worn.  Selling what I won't be wearing to make space (see other listings).  Thanks for looking.
