(K-Pop Quiz) Guess the idol by outfit (LET'S GO MULTISTANS)

Hello stand and welcome back ❤️
The rules: You will see the silhouette of an idol and his outfit from one
specific song. You have to guess the idol and the song name where this outfit is from.
ps: I DO NOT OWN ANY OF THE VIDOES OR PICTURES! THEY BELONG TO THEIR ARTISTS.
