To be honest, that part was mostly wild speculation. Some form of wardrobe simulator could also be considered non-essential at the moment compared to the other updates being worked on. It got ugly last year when people were screaming about Coliseum controls and trading systems.

The whole system for selecting apparel could probably use some redesign, like different tabs for different item categories. Or a search function. It's a bit tedious to scroll through the entire catalogue of items, whether it's items that you own personally or selected from a generic design wardrobe.
