Tonight, Arcade Fire will play a Halloween gig at the Hollywood Palladium before hitting the road for the UK, France, New Zealand, and Australia to tour in support of their new album Reflektor. If you're lucky enough to be attending one of these shows (or if you're hosting a listening party for their recently released, discofied new LP), we think it's only right that you dress the part. Sure, you could channel Win Butler, complete with undershaved hair and bedazzled Vegas tuxedo jacket, but we'd rather go the Regine Chassagne route, because emulating the haunting vocalist means sequins, impromptu sashes, and the ultimate accessory: an accordion.
