Two bits:

- your terms of service says that it's the user's responsibility to maintain a backup. Do you actually offer a data download service, or is this just legal fluff that you copied?

- when someone uses one or two seed items to look for outfits, and you don't know that they have other items in their closet already, you could (and probably should) offer to link them to a site that sells that stuff. Don't offer to sell them a seed item or something that you know that they already own.
