Sweetie Belle gives her sister a strange look.
You rub a hoof against your left leg nervously under Rarity's compliments. You've never been complimented by such a pretty mare before….
"Th-thank you, Miss Rarity."
"Now now, dear. Just Rarity will suffice," she says with a smile, "A friend of Sweetie's is a friend of mine. So, what brings you to my boutique?"
"We have a school fashion show," Sweetie explains, making Rarity's eyes light up as she inhales deeply with excitement.
"And you came to your big sister for help! Of course, of course, I'd be happy to help the two of you. And if you're wearing a design of mine, everypony will see it and want one for their own little fillies! Oh it's brilliant!"
Sweetie Belle coughs gently, "N-no, we have to design one ourselves. I just thought maybe you'd let us work here and maybe be….an advisor, kind of?"
She smiles at her older sister as Rarity deflates a little.
"Oh. Well. I suppose that will do. You can use that corner of the work room over there," she says, using her magic to move a set of mannequins out of the way, "I'll be working over here if you need me. Just try not to make too large a mess, okay?"
Sweetie Belle promises and the two of you head to the cleared out space, Rarity sliding small assortments of fabric after you for your use.
Sweetie unpacks her saddlebag, pulling a small notepad from it and flipping a few pages, "Alright! So, here are some ideas for outfits I've got."
>Sailor outfits>Butler and maid>Royal Ball theme>Scarves and sweaters
"So, what do you think? Do you like any of those, or do you have some other idea that we should try?"
