Avatar Editor

The Avatar Editor is a option where you can customize your character in MyROBLOX.

When you get a hat, this is the place where you wear them. You can also wear Shirts, T-Shirts, and Pants.

MyRoblox does not use your current Roblox avatar on the site. Instead, it has it's own character system to customize your character. This is because if it used the current Roblox avatar on the site, it would almost defeat the purpose of collecting Hats when you could just buy them on the site.

More information of Hats can be found here.
Hats are the main purpose of MyRoblox. You have to collect them. You can wear them, or just keep them as a collection to show off to your friends. You can wear these hats to show off your looks and style.
