Thanks! As I said before it's actually a charcoal suit but obviously you're not the only one who saw it as navy in this shot. Oh well. Buttons are Smoke MOP. The glasses are Garrett Leight.
Well, you nailed it. Almost all my dress shirts are cutaway collars with a higher stance than the shirt depicted here (you can check my tumblr if you're curious, there are a few shots there). I have a couple of club collars as well. This particular shirt is probably the only exception, and I actually think it doesn't work with a suit & tie for me and probably won't wear it with such in the future.
But... and I had to google it... a double round collar is probably a more affected look than what I'm going for. I do, however, have a club button-down collar shirt arriving next Tuesday...
