Questions I have during the VS fashion show

~disclaimer: I am not trying to body shame~
  1. Why are they wearing bras if they have no boobs?
    Really? Bras suck?!
  2. Why is Bruno Mars singing a song called "Chunky"?
    These girls have not one ounce of fat on them....
  3. Why are there so many unnecessary straps on these underwear?
  4. Why are lady gaga, Bruno Mars and the weeknd fully covered up? Was that their choice?
    Lady gaga is the queen of wild skimpy outfits... Were they afraid she would show them up?
  5. Who decides what they do at the end of the runway?
  6. Why do all of these boots look like black garbage bags?
