Sized medium, but fit large. I had it taken in by my tailor to slim the sleeves and back with darts, this fits more like a medium now. Light cotton (poplin?) with great dark buttons that are slightly reflective (see photos). It's a nice shirt, which I bought off the forum because I felt I should own a black shirt. I've never worn it once, except at the tailors. On it goes to someone else. There are two imperfections: one nick repaired by my tailor, and a bit of fraying. Discounted to move this fine shirt. This is surely the best way to buy a CDG shirt without splashing on retail. Get 'er done. Measurements: P2P: 21" Across shoulders: 17.5" Shoulder seam to cuff: 26" C2H: 31.5" Shipping to Canada is included, I'll split shipping to the CONUS (add $5).
