O.O..... wait a sec? .....um... *Calculates this* hmm........ It seems that my calculations are correct: I'm looking at Panty and Stocking clones here!
Twilight looks so much like Stocking, it's not remotely rocket science. And Rarity is being a homage to Panty. It's so clear, you can picture the same picture within the pictures that these pictures are showing. Are you picturing what I'm picturing, because I don't think any more pictures can some up this picture. XD
