"Go to Nightmare Night, you said. You'll have fun, you said. Ponyville will love you, you said. Look at this ridiculous dress I ended up with! She played dress-ups on me! When they weren't screaming at me, they were laughing at me!"
Celestia too, was about to start laughing.
"Yes, I can see Rarity's - err - handiwork all over the outfit. At least you dressed up for the event, right?" She raised her hoof in front of her mouth to try and stifle her giggling. It wasn't working.
"You said a princess should conduct herself with dignity and grace. How can I do that if I'm wearing this?"
Celestia couldn't hold it any longer. She started to laugh uncontrollably, much to Luna's chagrin.
"I'll get you for this later, Tia*."
"But it is a nice dress," Luna murmured under her breath when she thought she was out of Celestia's earshot.
"I heard that," Celestia called out from the other end of the corridor. Luna growled and continued her indignant walk away.
I'm not totally happy with the way I redrew the collar, but after a bunch of attempts, this is still the best looking.
