To make a Roblox shirt, first, log in to the Roblox website. Click on “Create” and then “Avatar Items” from the dashboard. Select “Shirts” and click “Upload Asset.” Download the shirt template from the classic clothing page.
Open the template in a photo editing software like Photoshop or GIMP. Design your shirt by painting over the sections which include front, back, left arm, right arm, and others. Make sure to be creative and detailed in your design.
Save your designed shirt as a PNG image. Return to the Roblox website and navigate to the “Upload Asset” page. Choose “Shirt” from the asset type selector menu and upload your designed shirt image.
Before finalizing, test your shirt in Roblox Studio to ensure it looks correct on the avatar. This step helps you see if any adjustments are needed.
Once you are satisfied, upload the shirt to the Marketplace for a fee. After approval, you can sell it to other players and earn Robux.
