It's the Eidos long sleeve one button placket popover, in cotton/linen. Every time it's posted it gets like 20+ thumbs. Anyways, like I said, I strongly dislike wearing a suit without a tie, but wearing it like this shows that you've intentionally chosen not to wear a tie, as it's impossible to wear one with this shirt. It's not an optimal look, but this is what people in my industry wear. It becomes a question of wanting to be sartorially correct, but standing out, or dressing like your coworkers, but being incorrect.
Yeah, I get that and all. I personally think of pinstripes as being very CBD. Seeing that suit with this extremely casual shirt doesn't sit well with me. I have a hard time seeing that shirt work well with any suit, solid or otherwise however. I could see it with a odd jacket and trousers though. I think a cutaway/spread collar shirt, a solid suit and no tie would look best if you want to go for that look. Not crazy about it either in general though.
