Psy updated his Twitter and Me2Day on Wednesday morning with two teaser posters for his upcoming 'Happening' concert. The posters indicate that there is a dress code for the show, all concertgoers are to wear white.

A little after 11am on Wednesday Psy uploaded the two posters for his highly anticipated solo concert in Seoul next month. One poster is titled 'The Awesomeness of White' and the other asks if fans have prepared white clothes to wear.

One poster shows Psy in what appears to be a fairy princess costume, complete with long, satin gloves and a crown, on a field of bright pink wearing his trademark sunglasses. His face looks serious, but his pose suggests otherwise. The text over top reads, 'Did you prepare your white clothes?'

The second poster is a series of nine photographs of him in various white costumes - everything from an astronaut to a football player and a figure skater to a stormtrooper.

Psy's Twitter post accompanying read: "#WhiteHappening.jpg lmfao!!! see this pic and let's be white on 0413"

The images are goofy, light-hearted and imaginative and indicate that this upcoming concert is definitely going to be one for the history books.
