Those look good, aon. Cornell's coat buttonholes are a little rustic, but quite acceptable and great for the price imo. I really like their handsewn the shirt buttonholes. I've never had a problem with them coming undone.
Hey Neyus, here are some pics of the linen jacket lined w/ shirting. Sorry for the delay:
(If you're wondering about the white line at the lower pockets, that's from how they first put on flapped pockets when I'd asked for patch pockets. At a fitting, I reminded Mr. C that I'd asked for patch pockets but didn't ask for a change. When I picked up the suit, I saw they had sewn on patch pockets. They were too small and too low, so I removed them. It was a little irritating, but for the price and since I was leaving, I didn't and don't mind much.)
What I really love about the jacket is that I can machine wash it. The only other things I'd change on it are to have a tighter, higher collar and remove the shoulder pads.
