To make a shirt in Roblox, log in to your Roblox account. Navigate to the [Roblox website](https://www.roblox.com) and click “Log In” in the upper-right corner. Enter your username and password to access your account.
Next, click the “Create” tab at the top of the page and select “My Creations.” From the menu on the left, click “Shirts.” Here, you will find a link to download the shirt template. Click on the link that says, “Did you use the template? If not, download it here,” and save the image to your computer.
Open a photo-editing program like GIMP or Photoshop to edit the template. Make sure your design fits within the template dimensions, which are 585 pixels wide and 559 pixels high. Customize your shirt to your liking by adding colors, patterns, and graphics.
Once your design is ready, test it in Roblox Studio. Open the Avatar tab and click Rig Builder to choose a rig type. Insert a ShirtGraphic or Shirt object and apply your design to the dummy character by selecting the image in the Properties window.
Finally, return to the Roblox website to upload your shirt. Go to the Upload Asset page and select “Shirt” from the asset type menu. Click the upload button, choose your designed shirt image, and enter a name and description. Click “Upload,” which will cost 10 Robux. Your shirt is now ready for use in Roblox!
