Oho, you're making Cecelia? I can't wait!

While with flash, the fabric looks purple, but if you're brother's the one taking and color/contrast editing the photos, it shouldn't be a problem (my Kosmos wig does all kinds of strange turn-arounds in color with other people's flashes, thankfully my boyfriend photog knows post processing editing enough to fix it...). I say keep the current fabric, you'll be fine, and it'll look fantastic ^^
