Thanks, what's wrong with the shirt? It's a light blue OCBD, except the buttons are behind the collar. I'm not a big fan of buttondowns where you can see the buttons, and I don't care much for collar roll either, except if it's a tab collar. I guess it's just a pet peeve of mine, but I just don't like seeing the buttons, it seems a little messy to me.
Looked like a chambray or some weirdly-coloured casual shirt.
