Banana Republic Rio Bonded Lining Trench Coat

I bought this Trench Coat at the end of last summer, worn only once to work. This year, it's way too tight on me, even in the shoulders - uncomfortable to hold driving veal - I put weight and unfortunately have to let this Trench go. Trench is in excellent condition, worn only once while driving to and from work. I would describe this trench as a light coat. The lining is bonded to the trench, making it a bit stiff and more substantial layer than a soft, unlined one. Measurements taken flat (fabric is not stretchy): pit to pit 22", waist 20.5", hips 23.5", length center back from neckline to hem 46.5", sleeve length 24 3/4", width across the shoulders from top of the sleeve to top of the sleeve 17.5", back slit length 18".
