In menswear, t-shirts are the default product you see and they are in a single color, but once you have chosen a design, you can choose between several other types of clothing (styles) such as sweatshirts, hoodies, sleeveless t-shirts and many others. You can also change the color of the product of course. The rule here is that for dark colors it is best to use the design with the white letters and for light colors the design with the black letters.
