Gawd, Trinity Blood cosplay gets so expensive, though I suppose it depends on which medium you go with. My artbook white nun Kaya has cost me far more than I want to think already, though a good chunk of it was lace and resincasting supplies -- and my fabric snobbery. :3 Though the time is even worse than the money ... bias tape, why do you take so long?
(Of course, I'm doing mine with an eye on entering craftsmanship judging, so that may contribute to my neuroses.)
