The in-game Torishop already lets you try on stuff and you can see how your Tori looks before buying, which is awesome. This could be made to work so you could try on anything purchasable, wether it be art, flames, etc...

Many people have asked to be able to do this. And we are so close to already having it. It just needs to be all connected. To be one.

Side note:

I think that the forums and the game should be found in one place, and should be viewed as one. By clicking the Toribash icon, you are taken to the game, and from within the game, you find the forums. They "are" one. Perhaps, there could be tabs, allowing to quickly switch between forums and game.
