I really like these choices! A little different than usual for each of them, besides maybe Rarity. I especially love that Twilight's manages to be comfortable and err on the side of casual but still something more "dressy" if you're the type that normally is too busy with studies to care about dressing up. Fluttershy's skirt is gorgeous and I love that choice in AJ's hat, I haven't seen one like that on her before.
