Finally! After hours upon hours, late night after late night, it's finally done!
A huge thank you to everyone who gave wonderful suggestions for their costumes! Sorry their not all exactly what was suggested or they don't look exactly like what they're meant to be. But that's kinda the point of them being costumes. They're not perfect.
The costumes are as follows:
Pinkie Pie - Deadpool
Rarity - Vampire
Spike - Panzer Dragoon
Twilight - Changeling
Sweetie Belle - Chell (Portal 2)
Rainbow Dash - Dragon
Scootaloo - Dodo
Applejack - Pirate
Apple Bloom - Little Sister
Fluttershy - Bunny (Sneaky bunny suit)
Happy Nightmare Night everypony!
