4Minute came back with "Crazy", a song that people are going crazy over. Many of my friends like that song (Desiree, are you reading this?). I made a couple of finds in their music video.
First up is Gayoon who is wearing the Perforated Leather Cage Bra by Chromat. In the K-pop industry she probably can't wear it by itself without the music video getting a 19+ rating so she wore a crop top over it.
