Karl Lagerfeld Wool Blend Coat

Bought this coat last winter, worn once (for about an hour lol). No stains, smoke free house, brand new condition. This is a size medium and I feel I could have gone with a small. For reference: I’m 5’8, 140 lbs, wearing between size 6-8. See below product description from Saks (where I purchased it). Let me know if you have any questions! Tailored coat with portrait collar and tie belt offers a refined option for commuters. Portrait collar Long sleeves Concealed front buttons Tie self belt Two angled front pockets Polyester lining Wool/polyester outershell Dry clean Imported SIZE & FIT About 39" from shoulder to hem Model shown is 5’10” (177cm) wearing US size Small
