There will likely never be a one-stop-shop option. That's just too much info to be handled at once. This is why dream fitting exists as it does, within the confines of the inn room. This is why we have youtube channels like this one. All this info is available outside the game already.

Not every player is this much into glam and those that are have little trouble venturing out to find what works. It's not a necessity and people get by just fine without it. Dream Fitting is the exception because you want to be sure you'll be happy with an outfit before you put down real money on it.
