To start, check out these handy templates which ROBLOX themselves has created. If you right click and save these images, you can use them as a guide on how the clothes should look once you upload ...

Before designing a shirt, you need to have a Roblox account and some Robux, the in-game currency used by players to buy accessories, clothes, and skins from the avatar shop.

T-Shirts are the easiest clothing to make in ROBLOX. Create an image that’s ideally 512x512 pixels and then upload it to ROBLOX via the Asset Manager in ROBLOX Studio.

Roblox allows players to freely personalize clothing items, allowing them to express themselves and stand out from others.
