ポロシャツ
A polo shirt is a collared shirt with a placket neckline that normally features three buttons. These shirts are traditionally short sleeved, but long sleeved versions are also available. Some of these shirts may feature a breast pocket.
Example: post #1395570
These shirts are frequently not buttoned up all the way, which may conceal the top button (ex: post #1165398).
