Question about Giles

I am writing fanfic, yay!
I have already killed one road block and am making a lot of progress. Not sure why, but the muse is with me today!
Does anyone remember in what context Giles wore his ridiculous burgundy Wizard's hat and robe? Was it a Halloween episode? It was something to do with the shop. The first opening? I'm sure I can find out if I search the net, but that always gets me side tracked.... Not good, when the muse is around....
