“Cheerilee never gets invited to parties. She wasn’t at the Gala or the wedding and I can’t recall any other party in which she was present. And she stayed home on Nightmare Night.
 
Anyway, this (in my mind) would be her dress she’d wear if she ever got an invite to a party. It took a long time to get this design right, or at least to a point at which I could say, “Yep, that’s a dress Cheerilee would wear.” Obviously it’s based heavily on her colors and her cutie mark.
 
It’s OK, Cheerilee. For now you’ll just have to go back to a world of making lesson plans, grading homework, bratty students, snobby parents, and intrusive crusaders. And not having a special somepony. Just keep up that brave and cheery facade and things will turn around for you eventually.”
