The Actual Process
Most people overcomplicate making a Roblox t-shirt because they treat it like a traditional design workflow. It isn't. The shirt template is a specific pixel layout, the publish limits are strict, and the platform does some weird compression that nobody bothers reading about. I spent about three weeks debugging weird artifacts on my first batch of designs before I realized the problem was mostly on my end, not Roblox's. You start by downloading the official shirt template from Roblox's creation tools page. It's a flat, unfolded PNG that represents all the faces of a default Roblox character. The dimensions matter more than anything else. Use 585 by 559 pixels for a standard design. Going higher doesn't help because Roblox compresses your upload down anyway, and going lower makes everything look soft and muddy on characters that aren't tiny. Open the template in whatever image editor you already use. Photoshop, GIMP, even Krita works fine. Don't bother with fancy vector workflows here since you're ultimately working in pixels. Paint your design directly onto the template layers. Keep everything inside the template boundaries because anything outside them gets silently chopped off on publish. I learned that the hard way on a design where I accidentally placed a border element 4 pixels beyond the edge and spent an hour wondering why it disappeared.
When you're done, export it as a PNG. Then go to Roblox and upload it through the Clothing item creation page. There's a preview that shows you what it looks like on a default avatar. This preview is useful but not perfectly accurate because it runs on Roblox's own rendering pipeline, which differs slightly from what players will actually see depending on their graphics settings.
What Nobody Tells You About Shirt Textures
Roblox applies a mild compression pass to every uploaded texture, and the amount depends on the file size and color complexity. A design with flat, solid colors and clean edges compresses cleanly. A design with lots of gradients or fine noise patterns gets smeared during that compression step. If you're doing intricate shading, bake it into slightly bolder color bands beforehand. It saves you from seeing your work turn into an impressionist painting after publishing. Another thing people miss is how the seams between template sections interact with your art. The front and back panels connect at the shoulders and sides. If you draw a pattern that crosses those seams, it won't align perfectly on the 3D model unless you account for the wrapping. I once made a horizontal stripe pattern that looked straight on the flat template but ended up at a slight angle on the torso because the side seams introduce a small offset. The fix was just to shift the stripe positions by a few pixels at the seam lines before exporting. There's also a maximum file size limit for clothing uploads. It's not huge. If your PNG comes in over a couple hundred kilobytes, you'll either need to reduce color depth or trim details. Using Indexed Color mode with a limited palette can knock the file size down significantly without visually noticeable quality loss. I typically keep my shirts under 150 kilobytes to leave breathing room.

Publishing and the Approval Wait
Once you submit, the shirt goes through an automated review process. This usually takes somewhere between a few minutes and a couple of hours, though it can stretch longer during high-traffic periods. The system checks for policy violations, inappropriate imagery, and texture conflicts. If your design contains anything resembling real-world logos, text from copyrighted sources, or suggestive content, it will get flagged. Roblox's filters are blunt instruments. Even innocent designs with certain color combinations or shapes can trigger false positives. I had one shirt with a simple geometric pattern get rejected for what turned out to be an overlap with a flag-like color scheme. Resubmitting after shifting the palette by a couple of hues fixed it immediately. After approval, your shirt is available for sale or distribution. You set the price in Robux if you're selling it. The default price points are things like 5, 10, or 25 Robux. Pricing above that requires a decent existing audience or proven sales history, since most buyers won't spend much on a single shirt without seeing a track record.
Practical Constraints and When This Approach Fails
Working with the flat template has real limitations. You can't create designs that change based on lighting, animation, or character pose. The texture is locked to a static UV map. If you want dynamic effects, you need to look into shirt decals or full clothing meshes, which involve a completely different workflow and a Builders Club or Roblox Premium subscription to access advanced publishing tools. The 2D nature of shirt templates also means you're working with a very approximate representation of how colors will appear on a 3D model. Your monitor calibration matters more than you'd expect. A design that looks perfectly balanced on a bright screen might come out washed out or too dark on someone else's display. I usually check my uploads on the Roblox mobile app as well, since the phone screen renders colors differently than my desktop monitor and catches issues the web preview misses. If you're designing for a specific avatar shape, keep in mind that the standard template maps to the default R6 or R15 rig. Custom body proportions from certain game engines or modded avatars will stretch or distort your texture in unpredictable ways. This isn't something you can fully control from the design side.
