Garbo Showerproof Trench Coat

99% of my barbour coats are a uk 16/us 12 (carolyn waxed coat is the only one that i bought in a smaller size uk14). the 16/12 was HUGE, also tried a uk14/us10, and a uk12/us8, both of which were still too big (width). i can’t go smaller as the sleeves would be too short. sadly, sadly, i am going to return these sizes, too. none of these sizes, when i try them on, fit, like the one in the video/with coat picture. i’m a 40b, so my boobs weren’t the issue, either.
