As much as I love the fabric on this K Jacket, and think it'd be an awesome spring\summer jacket, I'm accepting it's just not a good fit for me. I find this to be a bit big overall; because I have a different K jacket, size EU48, that is a bit smaller, and fits perfect. The shoulders on this jacket seem generously sized, despite their width, so I'm supposing this could work for someone in the range of 38-40. I've never worn it. Although I purchased it second hand, it appears it has never been worn: all pockets are sewn shut, the vents are tacked, it looks flawless, and the "inspected by" tag is still in the inside pocket. Measurements are: Shoulders: 17.5" Chest (P2P): 21" Waist 19" Back length: 29.5" (bottom of collar to hem) Sleeve: 25" (shoulder seam to cuff) Sleeve opening: 5.5" Please PM me for more info, or offers (I only occasionally sell on SF, and I prefer to ship within the US). Thanks!
