I think it'd be an extremely useful feature.

We can do this on the "Organize Items" page in the wardrobe (change "name" field to "userprice", select your ascending or descending option, then click the "update items" button), or did you mean something different?

I feel like since the prices of items are in near-constant fluctuation trying to keep tabs on the costs of such an expansive number of items for sorting purposes just seems like it would be really difficult to do in the actual Wardrobe itself.

I meant more in the context of when you're trying to find items for specific purposes in the "show all" section , sifting through large amounts of items and trying to find the cheaper (or more expensive) ones.

You're probably right -- I don't know much about how things like these are implemented. I just think it would be useful to have the option.
