Can anyone help me find a brand that has shirts like this?

I'm hoping that this doesn't end up a fruitless search, but I'm forever on the hunt for t shirts that are cut juuuuuust right. Came across this image the other day while perusing music stuff, and I'm really liking the cut on the shirt that front row, left is wearing. The collar is loose, but not too loose (something that seems difficult to find amongst the usual suspects for this kind of clothing), and it looks like it's a nice cut in general. Can anyone point me in the direction of brands that are likely to have this kind of fit? Any and all help would be appreciated.

I'm a knucklehead and posted this in the tab I had open in the wrong forum (should have been in the advice section, obviously). I'd delete it and put it where it's supposed to be, but deleting the thread doesn't seem to be something I can do on my own.
