I was thinking about this the other day, and I had a idea from the necklaces. The way the clothing and vanity works seems so different than the rest of the game. You just go on the page and change your looks, but you can only use credits? Why not offer some clothing/vanity for currants or img? I mean, make them more expensive or something, but you are really limited in options if you can't afford the credits.
Also, I figure there's probably a way to do this: In game items that change into clothing or vanity items. Take the necklaces, for example. You would be able to activate or spend them and it would remove it from you inventory, but add it to your vanity. That way, we might even be able to MAKE clothing. But, if you do that, make sure you implement a preview option... I hate not being able to see what I'll look like before I waste an item.
Thanks for reading my novel!
