This actual suggestion has been brought up with Yoshi P, in a live letter Q&A I think. He said that the existing system makes that extremely difficult since the appearance is attached to the specific item rather than the character's spec. Implementing such a system would be a pretty major project even if the system could be altered to accommodate it.

That said, glamour concerns are something that comes up pretty often so maybe it will get bumped in priority once they have finished the server upgrades/Inventory expansion. Still, even if they started working on it immediately we probably wouldn't see something till 5.0 at the earliest.

I would like such a feature though.

By the way, you can bypass the post limit by editing the original post. Basically type what you want to type. Copy and delete all but a few lines of it and post it. Then edit the post and paste the rest of the post back on.
