I've mentioned this in other threads but I'd prefer no restrictions at all... but that's likely not realistic considering the hurdles the devs have to go over with this game.

That said, I do wish that the hairstyles and outfits that go on the mogstation were unlocked completely. Race, gender. Whatever.
It just feels like you'd want to cast a wide net when you put up an item for real money... and what casts a wider net than making an item accessible to all? Would it be too much to ask them to put more work on these "premium" items?
