Batgirl & Supergirl costumes

First half of this video is devoted to two models dressed up as Batgirl & Supergirl. Then they move on to others:



A couple of questions:

Why is Supergirl wearing Wonder Woman boots?

Why is there screaming in the background?

Nice, but...

Why are most consumer costumes so shiny?

ooh yes,
Those are some pretty hot girls and I love the costumes. I really like how Batgirl and Supergirl are eyeing each other as if they are about to get physical, lol.

Great clip, thanks for sharing!
