This is an authentic Gucci T shirt purchased at the Chicago Gucci store. It’s a men’s size small but I’m a women sized medium who wore it for an oversized look. The difference between men’s and women’s Gucci shirts is that I’ve found the neck hole to be bigger in men’s shirts, which I like as a woman. There is a small spot on the back of the t shirt (pictured- barely noticeable) otherwise in amazing condition. CAN BE WORN BY MEN OR WOMEN.
