Luna Confronts Celestia (Coronation Dresses Ver.)

"Today is Twilight Sparkle's big day. You said we should dress to the occasion... and you want me to wear this? They won't be congratulating Twilight! They'll be laughing at me!"
Celestia too, was about to start laughing.
"Yes, you look very - err - regal in that outfit. Very princess-y. You will be centre of attention, for sure." She raised her hoof to her mouth to try and stifle her giggling. It wasn't working.
"You get exotic robes from the kingdoms out east. Cadance gets her crystal princess outfit from the northern Empire. And I'm stuck wearing something that predates Star Swirl the Bearded. How can I look like a princess in 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*."

I'm a bit late to this joke, but the expression on Luna's face is just too good to not use it here. For the record, I love both princess' dresses and I think both look absolutely beautiful in them.
