Which type of fabric is smooth, thin, and lustrous, commonly used for making shirts?

The correct choice is poplin, which is a fabric characterized by its smooth texture, lightweight qualities, and lustrous finish. It is tightly woven, making it ideal for producing garments such as shirts that require a crisp appearance while maintaining comfort. Poplin is often made from cotton, but blends with polyester or silk are also common, enhancing its drape and sheen.

While muslin is a plain weave fabric typically used for making patterns or prototypes because of its loose weave and less refined finish, it does not possess the smoothness and luster needed for shirts. Chiffon, on the other hand, is a lightweight, sheer fabric that is often used in formal garments and evening wear; it lacks the weight and structure suitable for standard shirts. Twill, which is known for its diagonal weave, offers durability and is often used for trousers or heavier apparel, rather than the lightweight and smooth qualities desired in shirts.

Thus, poplin stands out as the most appropriate choice for shirts due to its smoothness, lightweight nature, and a level of sheen, making it a popular choice in the apparel industry for stylish and comfortable shirt-making.
