“Hey, Rarity?” Twilight pressed her chubby hand into the backdrop, pushing it up against the wall as she waddled her way onto the makeshift photoshoot set. Feeling tired from carrying around her massive weight in some rather uncomfortable clothes, she was more than ready to get this whole thing over with. “How much longer is this supposed to take?”  
\  
“Aw, don’t be so glum, Twilight,” Pinkie chimed in as she looked up from her own stylish outfit. “If it helps, you do look really nice today.”  
\  
“Actually, she’d look even nicer if she did keep that glum look on her face,” Rarity explained as peered over her bright red spectacles. “You’d be perfect as a fabulously stern librarian.”  
\  
But Twilight could only groan heavily as she picked and pulled at her turtle-neck sweater-vest. “Ugh, I wouldn’t be so stern if it wasn’t so hot and itchy in this thing!” She bemoaned, peering spitefully at the other two as their outfits seemed a lot more freeing compared to hers.  
\  
“Well, I’m awfully sorry about that. They’re all still works in progress,” Rarity sighed. “But I needed to have them modeled for an assignment. Plus we’re all roughly the same size, so now’s as good a time as any. Especially if you’re going to get any bigger,” she added in a rather frank tone of voice. “Um, no offense.”  
\  
“Fair enough,” Twilight shrugged, rolling her eyes back.  
\  
Making a mental note of what to fix, Rarity then turned towards her other friend. “And how do you feel about your outfit, Pinkie?”  
\  
“Oh, I like it! It’s so pretty and cute,” Pinkie exclaimed, admiring the way the brightly-colored top hugged her large body.  
\  
“Well, I’m glad to hear it! Once I make a few more adjustments to it, you can feel free to keep it if you want.”  
\  
“Oh, thank you! It’ll be nice to wear, but I think I might like the outfit I bought with Fluttershy a little teeny tiny bit better.”  
\  
“Oh… Really?” Surprised at first, Rarity thought for a moment before realizing. “Ah, it’s the polka-dots, right?”  
\  
“Uh, yeah!” Pinkie replied, simply nodding in agreement. “Yeah, that must be it.”
