UNTITLED sleeveless shirt. The material is polyester, which gives a softer impression than cotton. It has a moderate see-through quality, but it's not so sheer that the inside is completely visible. The black buttons make it suitable for formal occasions. It's lightweight, quick-drying, and useful for travel. There is a mark on the left back waist area, likely from a bag, from being worn a few times. Please check the images.
