Polo is usually worn by people who work in a corporate company that has a strict implementation in clothes. It's a type of upper cloth which has collar and buttons. It comes in variety of colors and styles. Of course you wouldn't see someone wear this at home or in ordinary days. Wearing polo is best matched with slacks and leather shoes. It's not appropriate to pair it up with 'maong' pants and rubber shoes. Maybe, it's okay with 'maong' but not with rubber shoes. Anyway, polo can be worn even without 'sando' or white shirt underneath. It all depends on your style and taste. For me, I seldom wear polo... I do only when we have party and special occasions. But in my work (since they are not strict), I prefer shirt or polo-shirt. Why? Because I like so.
Shirt is another kind of cloth I really want to wear. Maybe because I get used to it besides the cool feeling you'll get from wearing it. Of course, I do not wear any shirt when I go to work (I'm a little bit choosy). Just plain shirts will do and other preferred colors. I don't like shirts printed with useless texts. Because it can only get the attention of others instead of noticing you in the first place. But maybe it depends... On the other hand, this one is best when match up with 'maong' pants and rubber shoes. It's absurd if paired up with slacks and leather shoes. Anyway, most of my upper clothes are polo-shirts. Shirts are secondary to it and polo is outnumbered by them.
There's no right cloth to wear. I'm just giving out my opinion about these two. What I am thinking when it comes to polo. What about in shirt.
