Fluttershy and Twilight Sparkle Equestria Girls Costumes

Sears.com seems to be a little bit late for Halloween, but have just listed Fluttershy and Twilight Sparkle Equestria Girls costumes on their site and ShopYourWay.com. Previously we've already seen a Pinkie Pie Equestria Girls costume at Kmart, so it's possible that they will receive Fluttershy and Twilight Sparkle soon too.
It seems very logical that they start to make more Equestria Girls costumes, as these are based on, well, actual human-like characters instead of ponies, making them a more 'realistic' costume choice.
