Chanyeol: NO.NO.NO. Put that gun and tongue away from my sight. You can never go wrong with the Joker's costume and props to the effort put. Finally his creepy expressions have find a better purpose than those memes lol
Baekhyun: You're another big NO. He also incorporated the glass with some red content as a prop, pretty great.
Chen: Oh boy, of course I should have seen it coming. He literally had milk cartoons and yogurts inside that huge bag lol. And I noticed a bottle of yakult on a table, I KENNOT.
D.O.: He doesn't even need to try that hard. It's more like he put the wrong shade of bb cream and felt like having a eyeliner day. Bb, your next movie/drama project should a horror one.
Xiumin: What are you? A rockstar? You look great nonetheless. #dageisalwaysofine
Tao: You did not just recycled your own outfit from 'Rewind', right? Btw, did they all use the same lipstick? xD
Suho: The leader as the Phantom of the Opera. Damn. He looks so good. I'm really hoping that the rumor going around about their new concept is true. 'Cause guys it means they will be forever in suits and I looove that. 

Sehun was there but no costume. Idk about Lay and Kai though. Hoping we'll get to see them in costume more, they're from SM for God's sake, learn from your sunbaes Suju and SHINee.
