It has a mind of its own

Yaz had never really been one to wear a dress. It had just never felt like her; still, with a choice between a dress that at least looked vaguely like it was intended for humans, or keeping in her old outfit indefinitely, she'd picked dress.

It was a dull silver, scaled fabric going down as far as her knees, though the straps left her arms feeling bare. She'd gone for a jacket to cover up a little more, leaving it undone in an effort to replicate a little of her usual style. Then there had just been the embarrassing business of finding underwear; Yaz hadn't had a clue where to look for that, though she'd soon found some, even if it barely qualified as string, let alone panties. Quite why the Doctor had that in her wardrobe was something she wasn't sure she wanted to know (and for that matter, why it was next to a short-skirted parody of a policewoman's outfit was beyond her too).

She'd been a little worried about going braless, but the dress seemed to offer a little support. It was definitely an alien material, but it wasn't something that could cling too tightly to her so at least there wasn't anything... obvious.

It'd do until she had the time to find something else. She fidgeted slightly, looking around the new world. The Doctor had already run off a little; Yaz hurried over to her, tugging a little on her dress.

The texture still felt weird. Still, it was absolutely better than nothing; the skirt was a decent length, the neckline was high enough, it was really all she could want.

"Doesn't look like Earth to me," Yaz said.

"Don't you think?" the Doctor said. "Right temperature, gravity seems close enough, blue sky, brown dirt..."

"Four suns," Yaz said.

"Four..." the Doctor paused. Her gaze travelled from the landscape, up to the dark blue sky. Sure enough there were four orbs of light hanging there, even if two were rather close to the horizon. "Alright, yeah, might be a bit off."

"So where are we?" Yaz said.

The Doctor shrugged.

"You don't know?"

"I don't know every planet in the universe!" the Doctor said. "Not at every point in time, at least."

She glanced around; Yaz followed her gaze. It was fairly empty, smooth stones composing the ground, but there were a lot of them. Jagged cracks, multiple layers... There were a few pits that glinted thanks to what looked like metal, though it seemed more like rubble than any proper machine.

Yaz shifted, tugging down on her dress slightly; it felt like her skirt was hiking up. She breathed out, returning her attention back to the landscape.

The Doctor was gesturing to something a little way off, a tower, a tall thin metal spire reaching up into the sky. She grinned.

"Looks like a radio mast," she said. "Patterns in technology tend to repeat. Anything tall and thin like that, it's only useful for transmitting. I'm sure we'll find someone there. Maybe they're broadcasting cartoons, I think I like cartoons."

She grinned, then ambled off. Yaz kept up, mentally hoping her dress would last.

She didn't realise, at first, as the back slowly withdrew, silver scales creeping up her legs until a hint of her ass was visible. Thanks to the inadequate underwear that had been all she'd been able to find, her cheeks looked as though they were bare, the skirt continuing to ascend-

At the feel of the cool air, Yaz yelped and hurriedly tugged her skirt down. It took a bit more **** than she'd expected to yank the material lower, regaining her decency.

Flustered she glanced over her shoulder, cheeks warming as she remembered Ryan and Graham were following along behind her.

Awkwardly she turned her gaze forwards, holding the hem of her skirt lower for a few moments more to make sure it didn't hike up again. And was it her imagination, or did the skirt feel a bit shorter?

She glanced down-

And yelped again. The Doctor turned.

"Yaz?" she said.

It was... ok, the neckline had a little more of a V to it than she remembered picking out, but that wasn't much. It wasn't anything nearly as bad as discovering she'd just accidentally flashed her ass to her friends; rather, the familiar silver she'd picked out was now... not silver.

"Why is my dress blue?" Yaz said, slightly unnerved. "Is that a reaction, or..."

The Doctor frowned for a moment. Then, suddenly, she beamed again.

"I knew I recognised that!" the Doctor said. "Symbiotic dress, Benny bought it from the Worldsphere. Super-advanced civilisation, just, really, super-advanced, they had clothes that shaped themselves according to whatever the wearer wanted. Almost forgot I had that. It must have sensed you wanted a blue dress."

"I... huh," Yaz said. She blinked. Well she definitely preferred the dark blue to the gaudy silver. "Wait, symbiotic? Doctor, is my dress alive?!"

"No- yes- kind of?" the Doctor tilted her head. "Advanced technology. Not sentient - it'd be so boring being a dress don't you think? - but it's about as advanced as the living machines there. Don't worry, it's totally safe. Benny wore it all the time."

"Did she?" Yaz said, and hesitated. "I don't know who that is."

"Oh yes," the Doctor nodded, grinning in what was no doubt meant to be comforting. Then she hesitated. "Or... actually I think her exact words were 'How drunk was I that I actually bought that? Not even on a bet.' But it's definitely safe! Molds itself to look like whatever you want."

That... wasn't entirely comforting. Still she could make it through one trip with this, then hurry right back to the wardrobe and find anything else.

So long as it could tell the difference between what she actually wanted, and her increasingly panicked worries of how much could be exposed if the dress was a bit different. But- no, no, that wouldn't happen.

She didn't notice as the skirt, once more, slowly started to recede.
