Kukkii-san I tried to pick a color blend that would match the cosplayer's own hair and skin tone (she sent me photos and a lock of hair to match.)

The individual curls decorating the beehive were sealed with adhesive caulk, but I sewed them to the wig with transparent thread, so they can be removed and replaced at will.

The giant beehive is made with foamcore and extensions, same as the Bayonetta wigs in my gallery.
