Two girls waited for their friend at the Carousel Boutique. Jingling bells sounded her arrival. Rarity smiled and rose. "Ah, Applejack, good. We had hoped you could make it."
"Hey, Rares; hi, Twi. Rarity roped you into this too?"
"Well, she said she needed my help with some of the magic and material science and when she explained what she intended, it seemed like a very interesting project."
Applejack crossed her arms. "It ain't a dress, is it? 'Cause there is no way I can fight in a dress and heels, no matter what Rainbow Dash's animes say is possible. Heck, some weeks it's all I can do to keep a pair of jeans in one piece on the farm."
"No, not a dress, dearest. I realized quite early on, that anything that gives those dreadful monsters a way to grab you would be a detriment to your fights. But I did give thought to your modesty."
"Modesty?"
"Yes, your normal ensemble, while acceptably chic for daily life at Canterlot High... Well it, leaves quite a lot to be desired when fighting twenty-story tall monsters. I mean, so far, the only saving grace you seem to have is that you always wear boyshorts under your skirt."
"What does my underwear choice have to do with fightin' monsters!?"
"Well, boys being boys, they've been, ahem, taking snapshots."
"What!? Them no good lousy polecats—"
"Which is why I discussed a few alternatives with Twilight, options for something you can fight in that is a little more modest in some respects. I give to you, this."
"Rarity, I might be a simple country farmer—"
"A simple country farmer ho can effortlessly order my favorite half-sweet white mocha frappuccino for me without blinking."
"Point is, I know a catsuit when I see one."
"This is not a catsuit, Applejack, this is a unitard. One based on the designs of the current 'superheroes' that are popping up in Canterlot. I padded out certain areas to preserve modesty and Twilight helped design some enchantments that allow it to grow with you and not be gripped by outside forces. Twilight?"
"So, Applejack, as Rarity already said, it will grow as large as you can and stay as tough, but it also breaths like Anugyptian cotton. The feet and hands have been enchanted to help resist internal impact as well as being doubly reinforced."
"That's all well and dandy, but I believe you have one problem. How do I squeeze myself into that quick enough?"
"Ah, that's where this belt comes in. We thought about how hard it would be to get on and off, so we designed a teleportation array into the belt buckle. As long as you're wearing the belt, you can teleport the suit onto you."
"... Well, the apple embroidery on the suit and the apple etching on the belt do look nice."

Applejack tilted her head as a thought struck her, and she narrowed her eyes at Rarity. "Wait, are ya sure it's only the boys takin' pics up my skirt?"
Rarity's grin suddenly became strained as her fingers surreptitiously tapped together. "Wh-why whatever to you mean, dear?"
Applejack didn't need her connection to the concept of Honesty to see that her girlfriend was sweating bullets. She held out her hand, a flat expression on her face. "Lemme see yer phone, Rares."
Rarity nervously glanced around, between her girlfriend and the rather uncomfortable looking Twilight, before slumping. "I actually don't have it on me right now; I keep it in the back room when I'm working on designs so I don't get distracted. But... yes, it has quite a few images like what you're implying on it."
Applejack sighed, rubbing her head. "Yeah, I shoulda seen that comin', really." After a moment, a playful smirk spread about her face. "Y'know, though, if'n you wanna see stuff like that, you just have to ask."
Rarity, a blush coloring her face, giggled at that. "Oh my, how scandalous~."
"Okay, if this is what it's like being around me and Sunset when we get all 'lovey-dovey,'" said Twilight, complete with air quotes, "I'm starting to see why Rainbow Dash gets annoyed by it."
