Luna had been pacing back in forth in her almost empty closest. "Tis silly," she said to herself. "Celestia is normally the one that attends the gala. She is the one that enjoys getting made up." With a sigh, she would exit the large closet. "And it appears that my guard has yet to return as well..." She would exit her chambers and make her way to the grand ball room where castle staff where getting the room ready as she looked it over.
"Thy preparations are must wonderful. Keep up the excellent work. We want this event to be grand and show our human guests the finest in Canterlot hospitality and class." Looking to her left, she would notice an idle set of hoofs. "You," she would call out. "Fetch me the royal seamstress. I am in dire need of her services. Send her to my chambers at once." "Yes Your Majesty," he would respond as he bolted off to find her.
As she waited, she would walk over to the large table that had been set up. "Well done. I have but one request, make sure the tables are set up in a horseshoe, with the heads of state, as well as ours 'esteemed'," a bit a venom was injected into that word, " guests and the heroes of Equestria nearby."
Moments later an out of breath servant would approach the lunar princess. "She is on her way to your chamb-" as he would collapse for exhaustion. "Thank you. You may have the rest of the day off for your serves," as she turned and began walking back to her room."
As she opened the door, an unfamiliar voice would greet her. "My your highness, this is an unexpected honor," the voice would say in a french accent. "It is normally your sister that I-"
Luna would cut her off there. "I am in quite the condrum, and I understand that this is short notice, but I am to be Gala ready by the time the party starts. I am in deepest need of, as you call it now of days...a makeover?" The seamstress would smile and nod.
"Not to fret princess, I have waited for the day that I could make you a dress. I am sure that I can whip something up." The door behind Luna would close and she began working on Luna's outfit and even her mane.
