Today I took the plunge. Spent about 3000 TP on mirrors to do up the 2-3 outfits each of my favorite characters kept around. Most worked out very well - all except some older outfits for my monks. The boots changed to sandals and the sleeve/midriff/pantleg lost all the orange accents from the 2 outfits I tried it with. Yes, I had it fail twice... after all the other successes I remembered another character had a similar outfit so tried again... both the outfits failed, with slightly different failed results (white/gray).

I may actually keep one of the failures, kinda like it. But neither truly worked accurately.
P.S. When one character pulled out their old gleaming golden mithral breastplate it had changed appearance while stowed in the TR cache. Was ugly gray sleeves and the arm/shoulder armor plates changed. Not sure if this was a related issue, but was very unhappy with that shock. Also several owlbear clad hide armors no longer looked anything like what they did when they went into storage; they now look like the leather armors you can pick up nowadays instead of the furry hide look they had.
