To make a custom t-shirt in Roblox, start by creating a square image. Roblox recommends using a size of 512×512 pixels, but you can use a larger size like 1024×1024 for more detail. Design your image using any graphic editor you prefer.
Next, upload the image to Roblox. Go to the Avatar section and click on “Create” under the T-Shirts category. Select the square image you created and upload it. The upload process may take a few minutes to complete.
Once the upload is done, you need to test the t-shirt. Go back to the Avatar section and click on your new t-shirt to apply it to your avatar. This allows you to see how it looks and make any necessary adjustments.
By following these steps, you can easily create and apply a custom t-shirt to your Roblox avatar. You don’t need Photoshop or Roblox Premium to achieve this. Enjoy personalizing your avatar with your unique design!
