Back in the day I had a most awesome physical magician with a fair addiction to shoes.

Was good fun, and soon spawned beyond that into clothes, a specific spell focus for the makeover spell. Had a column on my character sheet listing all my outfits and armor ratings.
Always smiled when the group asked "Thought you were getting bigger elementals, or learning that spell we needed last run?" And I had spent all my loot on 10 tres chic outfits and painting my bike again...
At least my GM gave my lots of karma for rping it well, as I
always needed karma!
