No support. Sorry, but I'll explain why.
First of all, would there be like, a Beauty Contest? Where all the owners who care to use their tu on these items can enter in a creatu, and some person judges, and then there's a tu prize, etc. etc? If so, pointless. It'd be like.. like.. Webkinz or Neopets, where they already do that.
Second of all, beauty items aren't that expensive. You can pick up artichoke loipstick for under 1k. So if say, you hoard all the beauty items you find in the isthmus, your pet gets more beauty? And unlike books, most items don't go poof. So you could continuously use the same item over and over again. And even if they ARE retired, unlike the book community, people pa.ss the items along, or lend them out to users. But they don't go poof.
Third of all: What would be the point of that? If you have a beauty stat, why not add a cool stat, etc. etc. It'd be like pokemon, where you give them pokeblocks to get their stat up. Except Res doesn't have Contests, like pokemon.
The thing about the trophies, etc. Would that be placed onto your profile trophy thing? OR would that be like, and item? Profile trophies, I understand. Items? Not really.
