Arcade Fire have issued a dress code for their upcoming arena tour, NME reports. A note on the Ticketmaster website states that purchasers of tickets will be expected to "wear formal attire or costume" to the shows, which the band is playing in support of their recently released "Reflektor" album. Arcade Fire similarly imposed a dress code onto the warm-up shows that they recently played. Frontman Win Bulter commented on the mandatory fancy dress rule at a warm-up show that the band played in the U.K, remaining defiant about the decision to implement it: "To anyone who felt uncomfortable dressing up - I'm not sorry. At least 70 percent of you are getting laid tonight ... As long as you showered. That's the secret. Boys." What do you think? Is it OK for gigs to have a dress code? Or would being told what to wear put you off from going to a show? Let us know in the comments.
