Trends: Buttoned Shirts To The Top

I’ve been noticing more and more people buttoning their shirt to the top like in the image pictured above.I call it a trend because I see in trickling down from the more forward dressers to the more mainstream guy. A lot of my friends from Japan have been buttoning their shirts to the top for as long as I can remember, not sure if it was motivated by style. When I was growing up only the “nerds” buttoned their shirts all the way to the top, now it seems to be a standard especially since being a “nerd” is now considered cool. I took some pictures from the Sartorialist to further my point.

Your thoughts?
