How to Make T-Shirts in ROBLOX T-Shirts are the easiest clothing to make in ROBLOX. Create an image that’s ideally 512x512 pixels and then upload it to ROBLOX via the Asset Manager in ROBLOX Studio.

On the Roblox website, there are several templates. One can use those PNG files, which have a transparent background, as inspiration while creating the design for the shirt.

Once you are done, just upload it to Roblox and you're sorted - just make sure the image is 585 pixels wide and 559 pixels tall else you will run into problems as it uploads.

Head over to the Roblox website and create an account for yourself. Then all you need to do is click on the 'Avatar' tab on the left side of the screen, where you’ll see your avatar ready to go.
