In addition to the ability to create and play games, Roblox also allows users to create and sell virtual items such as clothing and accessories for avatars, one of which are shirts.

Go to the Roblox Studio and access the asset manager through the view tab. A T-shirt is the simplest design to create but fairly basic. Roblox utilizes images in .png, .jpg, .tga, or .bmp format.

Roblox is delivering on a long-promised feature that allows creators to sell physical merchandise in-game.
