The problem of clothing in a world of casual sexuality...

It felt like every time Isaac went out into the streets of Ponyville, it looked a little different. His question about height differences had really caused some diversity among the ponies, with shortstacks walking alongside towering mini-giants like nothing was out of the ordinary. The buildings were also all bigger, making Isaac feel smaller, yet there was always another pony smaller than him, which was just... fun in and of itself!

Even with all that fun in abundance, even with the half-naked or fully naked ponies all around him flirting and showing off their bodies as he walked by, the problem of Rarity weighed somewhat heavily on Isaac's mind. By recklessly creating a world where spontaneous pleasure was common and everypony was proud to be a sex object... he'd accidentally also created a world where clothing fashion was marginalized.

The height question probably hadn't helped either, in retrospect, creating decades of growth spurts for everyone. Why bother buying clothes if they would be completely obsolete for your body within a season? Clothes would only be consistent for the fully grown and mature, and by then they'd be so used to going naked that it'd probably be an afterthought.

Now, why did Isaac care? After all, ponies going around with next to no clothing just made his sexual paradise more sexy, didn't it? Well...

For all his flaws, Isaac considered himself someone who believed in the importance of art, of creative expression. And having basically destroyed a form of artistic expression didn't sit well by him. Especially when it had the side-effect of ruining the livelihood of a beautiful lady.

Even though they hadn't interacted much in this world, Isaac really liked Rarity. He'd gone after Twilight first because of the same top-down approach that led him to the Princesses first - making sure that anyone sufficiently powerful would be on his side rather than potential threats. But if he'd gone purely in order of favoritism, Rarity might've been his first stop. Or Applejack. Maybe Fluttershy... Okay, they were all great and any ranking was going to be by narrow margins. But Rarity was still the one who'd really sold him on the pony concept, showing how even something as frou-frou as high fashion was something an artist could pour her heart and soul into.

Sure, he could change her interests, her career, into something sexier - enchanted jewelry, fetish outfits, even changing the very concept of 'fashion' - but then the mare he'd be dealing with wouldn't be quite Rarity, would it? And he wanted Rarity to be deeply and emphatically his lover and sex ****, not just a mare who looked like her. Same for all the ponies, more or less, but it came into sharp focus with the fashionista.

With a sigh, Isaac realized that he was going to have to figure out a way to make these ponies put clothes back on. Hopefully in a sexy way. So as he walked, he thought and pondered at his word choice.

As the ornate Carousel Boutique came into view behind the other cottages, Isaac felt like he had a potential candidate. Knowing no one would mind if he just asked random questions out loud in the middle of the street, he said, "Is it true that there's still a reasonably high demand for comfortable, sexy, and fashionable clothing among creatures of this world, especially clothes and accessories that highlight and enhance the body to catch the eye of a potential Master, with trendsetters dreaming up new creative themes to make sure their Master always has something new and sexy to look at? Is it true that ponies having long growth periods is a non-issue in the clothing industry, since there are things like enchantments to help fabric grow with their wearer, or tailors being able to magically adjust and extend fabric, or even easily recycle clothing into new alternatives?"

Isaac had to take a deep breath after that word salad, but when he caught his wind and looked around, he saw that his question seemed to have the correct effect. Ponies were by and large wearing a lot more clothing, no matter if they were three feet tall or nine.

Oh, there was still a lot of exposure. Nipples, pussies, cocks, asses - it wasn't hard to find someone's bits at a casual glance. There were even a couple of ponies still going fully naked, seemingly as a matter of preference. But now most ponies seemed to be interested in using clothing to highlight their bodies. Silky blouses that left chests exposed, hip-hugging denim, ribbons in manes and tails, open flannel shirts drawing the eye towards deep-cut abs, tank tops designed to look ready to tear apart if you so much as breathed on them, footwear that traced the shape of the feet and calves, big hats that cast a shadow over plunging cleavages...

Somewhat bizarrely, the surroundings were actually a little hotter than moments before, when the townsfolk had been largely nude. Now he couldn't just see everything at a glance, but there were colors and patterns and textures of all kinds inviting him to look, study, figure out their assets and obsess over them. Especially as ponies noticed him staring and silently flirted with him, twirling to show off their looks and toying with the edges of their clothing to suggest taking them all off right then and there.

Isaac had never really been a big believer in the power of fashion and clothing, especially when it came to his juvenile pornographic fantasies. But now... damn if he wasn't kind of a convert. And at the very least, it made what would be his world healthier with having a form of creative expression back, so it was all win-win-win.

Satisfied, Isaac finished his walk towards Carousel Boutique. When he got there, he noticed through the window that the fashionista's shop was still open and busy in the afternoon, with the occasional pony stopping in to browse or place an order. Mission accomplished.

Though now that he'd restored Rarity's fashion career, that just left the issue of what her 'specialty' was going to be in among the six Elements of Harmony... He'd made Twilight into an oral fiend almost by proxy. Rainbow Dash had a firecracker pussy. Pinkie Pie was all big softness. And he already had plans for the other two afterwards: Applejack would be all amazonian muscles and ass, and Fluttershy would be all about her breasts.

But what to do with Rarity?

...It didn't escape Isaac's sense of irony that, right after restoring her passion and career, here he was contemplating ways to overwrite other parts of her personal reality into something that would please his selfish sexual whims.
