Rarity looked at Bluebelle, who was shaking nervously.

"I must say, I don't think we've met, darling. What's your name?"

The nervous mare found one side of her mouth not working. "Blueblood" she mumbled, in a nervous sweat.

"Pardon me?" Rarity queried. "I didn't quite hear that." Clearly she had, and didn't like what she thought she heard.(1)

After a gulp, the response came. "I mean I'm... Bluebelle! I was, uh... recently unofficially coronated? Blueblood is my, uh... cousin! I doubt he'd ever show his mug around here, considering what he said happened at the Gala!" Bluebelle's wings were instinctively rising with her nervousness.

Silver Hawk was silently shaking with mirth, a goofy smile on her face. Clearly she'd likely get a well-deserved tongue lashing later, but it was more than worth it. She was quickly thinking up an elaborate excuse for that time.

"Oh! You're an Alicorn too, eh? I was wondering what you meant by 'coronated'."

"Uh, yeah! And i'm getting to be a... second time debutante, you might say. And I kinda... need some new dresses?" Bluebelle grinned (hopefully convincingly).

"First time you got a fitting, darling? No need to be nervous. I'll be gentle. Let me get my things and we'll take your measurements."

As Rarity trotted away, Bluebelle let out a sigh of relief. Turning and glaring at Silver Hawk, she silently queried through her teeth, her left eye twitching, "Why." She was clearly ticked off but didn't dare say more than that. (2)

Just as quietly, Silver responded, "If it worked out, you'd be able to avoid meeting your doom and hopefully get her to even like you. If not, it would at least be funny and Rarity would release some stress and besides, since you're an Alicorn you can take it. She could probably pound you for an hour and you'd be a little warm, but not at all astonished. Everypony wins!"

Bluebelle sighed. "Fair point.

Just then, Rarity returned with her measuring tape and an array of different implements (Including some rather sharp-looking needles) and an aray of colourful cloths and threads.

"Now, stay still, would you, dear?" Rarity said. "While I'm making your dress we can talk about how much of a jackass your cousin is." turning to the side, looking out a nearby window, she said, "No offense!"

"None taken." the slightly distant reply came.

One side of Bluebelle's mouth twitched. Clearly she'd still have to be careful.

"Anyway, where were we? Right, your cousin." she said, swirling the measuring tape around Bluebelle's body quickly, making notes on a notepad also levitating in her psychokinetic grasp. "So. It was the beginning of the night and I was looking forward to meeting the prince. It's always been my dream to get into the clique, you might say."

Being careful to move as little as possible, Bluebelle said, "Oh?"

"Why, yes! As much as i adore Ponyville, it's a little bit of -as much as it hurts to say it- a... one horse town, you might say?" she chuckled at the irony of the pun "Rather behind the times. Well, not entirely-" She stopped briefly to look the stock-still mare at eye level. "Did you know that we have an arcade, a bowling alley... but very few washing machines? The spa has some, naturally, and a certain rather Spoiled family I could name, but many of us don't. To be fair, many of us don't wear clothes. There are other things to note, but I believe you get the picture. Anyway... - So you can imagine that I'm looking forward to meeting him... only for the niggard(3) to make me to feel like a paper-bag princess the entire night! At one point he presented a rose to me. I thought he was going to give it to me... only to put it on himself! And no matter what he says, that shade of red does not go with his eyes."

"Rather churlish of him!" Bluebelle said, trying to get into the spirit of it. At least she could laugh at the brute she once was.

"Yes! Yes. That's it exactly!" Rarity exclaimed. "He insisted that I open the door for him, that I pick up after him- you see where I'm going with this?"

As the process went on, Bluebelle found it easier to laugh at her former self.

Within a half hour, Rarity had several outfits for her client to try on. Bluebelle somehow felt downright comfortable wearing each! For a modest extra sum, Rarity threw in a pair of saddlebags with a Holding enchantment to put them all in.

Eventually, Bluebelle was near to prancing out the door, beyond happy with the purchase.

"Feel free to come again next time you're in town. Maybe get Pinkie to arrange a party for you. She's opened a branch of her own, you know."

Before Bluebelle stepped out the door fully, Rarity said something that caused her to freeze in place for a moment. "Considering the mare you are now, I'd be willing to forgive you for all that, you know."

After a pause, Bluebelle sighed and said, "That makes one of us."

Closing the door, she and Silver prepared to return to the castle.
