Polo shirts are between T-shirts and shirts. They are a bit less rigid than shirts, but more ritualistic than T-shirts.
Polo shirts should be ranked among the top three in the entire men's clothing market. They are a versatile style that can be worn both formal and casual. They should be a must-have for every man's wardrobe. Although Polo says that the cut looks relatively simple, in fact, some small details can make the entire look look different.
In terms of fabrics, most Polo is pure cotton, but it can be woven in a variety of different ways. The most famous one is PK cloth, also called Pique. If I remember correctly, the first brand to use pique cotton was Lacoste. Their founder, René Lacoste, designed Polo shirts and used pique cotton. This fabric itself is soft in texture, breathable and sweat-absorbent, and has been well received by consumers, making it a classic Polo shirt style.
Polo shirts are roughly divided into two types, loose and slim. The loose style is a straight-leg design with a collar, placket, and two or three buttons.
The earliest Polo shirts were produced for tennis sports, so they were designed to be short in the front and long in the back for the convenience of movement, and the side openings were relatively large. However, the ones currently sold on the market have largely reduced the sports elements and focused more on aesthetics. The front and back are the same length, and the openings on the sides are just for a good look.
A slim-fitting Polo shirt will fit your figure better, and I personally think it looks more fashionable when worn on your body, but it also has higher requirements on men’s body shape.
In more formal occasions, you can button up the two/three buttons on the front of the Polo shirt to make it look serious and formal. If it's a casual occasion, you might as well unbutton the first button to create a relaxed and comfortable atmosphere.
