We're talking shirts as in button-ups? If so, yeah I think it's a great look. I do it all the time, especially when it's warm out. I'm not a fan of short sleeve shirts, I do have a couple, but I would never wear them in a professional setting. In a casual setting among friends and such, I think they're ok. It really comes down to personal preference. If you like them, wear them. Who gives a [bleep].
