A half sleeves polo shirt is a type of shirt that features a collar, a placket with buttons, and sleeves that end at the mid-bicep or just above the elbow. It is similar in style to a classic short-sleeve polo shirt, but with shorter sleeves.
Collar: The collar of a polo shirt is typically ribbed and has two points. It is designed to be worn either fully buttoned up or partially unbuttoned.
Placket: The placket is the panel of fabric at the front of the shirt that contains the buttons. It is typically two or three buttons in length and can be left open or buttoned up depending on the wearer's preference.
Fabric: Polo shirts are typically made from breathable materials such as cotton or polyester, or a blend of both.
Hem: The hem of the shirt can be straight or slightly curved, and typically ends at the hip or just below it.
