To make a T-shirt in Roblox, start by designing the T-shirt decal. Use an image editor like Photoshop, GIMP, or Microsoft Paint to create a 128×128 pixel square image. Utilize tools such as the Paint Bucket, Text Tool, Brush Tool, and Marquee Tool to add details and patterns to your decal.
Next, save your image as a PNG file. In Photoshop and Microsoft Paint, go to **File** > **Save as** and select **PNG**. If you’re using GIMP, select **File** > **Export as** and choose **PNG Image**. This step ensures your design is ready for upload.
Now, upload your shirt to Roblox. Log in to your Roblox account and navigate to the **Avatar Items** section. Filter for **Classic T-Shirts** and click **Upload**. Select the PNG image file from your computer to upload your design.
Finally, test and finalize your T-shirt. Check how it looks on your avatar to ensure it fits well and looks right. If needed, make adjustments to the design and re-upload until you’re satisfied. By following these steps, you can create and wear your own custom T-shirt in Roblox.
