Tan 70s Trench Coat w/ Unique Details

Beautiful tan trench coat with brown/ tan buttons down the front. Size 8, but fits more like a 4/6 (I am 5'9" and roughly 145 pounds 28/29 inch waist in the pictures). Meant to be fitted, not oversized. Fitted waist, and flairs out a little from the waist if buttoned. I love it, but I have long arms and I find it to be a little short for me, as well as tight in the shoulders. Would be great for someone a little smaller than me! It's in great condition, and I love the stitching on the shoulders. There is a fabric belt that goes with it, but I've been moving/ traveling and do not know where it is. I can try to find it if needed/ wanted (I know it is somewhere). Please reach out with any questions or for more pics/ measurements! Truly a special piece, and I want it to get used!
