An unfortunate choice of material

The world looked like a desert at first glance, vasty sandy dunes surrounding them; it was only when she stepped out onto the surface that Yaz realised that wasn't the case. It wasn't sand, it was some kind of vegetation, some mix of bracken and grass that might have been dead or might just have been naturally beige.

The Doctor took a few quick steps forwards, then looked up at the clear sky.

"Ok, planet's rotating that way, Sun's there... probably just a couple of hours of daylight left," she said. "Who's up for resting? Place looks quiet. Kinda boring really."

"I'm happy with quiet," Graham said.

"Wouldn't mind a break," Yaz said.

She squirmed slightly. It suddenly felt like her top was... warmer, ever since she'd gotten out of the TARDIS. Maybe it was just the sunlight. No one else seemed to be reacting, either way.

The Doctor started walking away, towards the top of a 'dune,' to get a better view of their surroundings. Her three companions followed, Yasmin at the back as she tried to straighten the waistband of her trousers. They kept twisting.

At the top of the hill, the Doctor squinted. There was definitely something in the distance, though this far away it was hard to make out what.

"Well, it's quiet over here," the Doctor said. She sounded faintly disturbed. "Hope they're not in trouble. Always seem to land where someone's in trouble."

It was about then that something exploded.

Ryan swore loudly, while Graham, Yaz and the Doctor began to back away. It hadn't been too far away, the base of the hill they were on, but the sudden rush of air hitting them was enough.

"Oh come on!" Ryan shouted.

"Back to the TARDIS?" Yaz said, a little hopefully.

"One second," the Doctor said. She tilted her head, one hand raised in a gesture for them to wait; after a few more seconds without any more explosions, she relaxed.

Then she started running down the dune, to where the... thing had hit; she crouched by the exploded object, frowning curiously. Graham rolled his eyes.

"What kind of person runs towards a bomb?" he said.

"I can still hear you!" the Doctor called back, not turning. "And it's not a bomb, that was just a high speed impact. If anything it's... Ok. You know how I said I always seem to end up in trouble?"

Yaz squeaked, then bit her lip. Ok, her shirt had definitely just moved on its own, she was sure. What was-

"Can I just- give me a moment," Yasmin said quickly. She needed to sort this out.

The Doctor looked up at her, but apparently saw nothing amiss. That was... probably good, right? Then again Yaz doubted she could remember every little outfit in her wardrobe. Hopefully she wouldn't have anything dangerous though. Right. Right?

Yaz stumbled back, biting her lip as her trousers seemed to squirm again, causing rather... distinct friction.

She heard the Doctor say something about a 'Nestene,' vaguely heard something about controlling plastic, behind her. Yaz meanwhile focused on going down the hill, up another, then down the next so that she was out of view.

Ok. After a quick glance around to make sure she was still alone, she turned her attention back to her clothes.

What was going on?! She straightened her top, tugging it down to make sure there were no awkward creases. Then, with another glance around, she pushed her trousers down to her knees. Ok, no, her panties weren't getting in the way either, no awkward bunching up; they were new too though.

She pulled them back up, squeaking slightly as they seemed to pull themselves down. What-

Wait, what had the Doctor said? They'd landed on a planet where some Nestene-thing controlled plastic? She thought the clothes had felt weird, maybe they were made of some kind of future-fabric based on plastic. Great. She should probably go back inside to change-

He shirt twitched, and suddenly she felt it give a sudden lurch up, making her yelp and move her hands to it, struggling to keep her protesting top over her chest.

And then her trousers definitely pushed themselves down again. That time they reached her ankles; nervously looking around to make sure none of her friends had come to check on her and were getting an eyeful of her panties and bare legs, she crouched-

Then tripped as the plastic garment twitched. The moment one foot left the ground, her trousers actively pulled away from it; when she tried to right herself, suddenly they slipped over her other foot too.

Yaz yelped, managing to regain her balance only to see her trousers crawling over the ground. away from her. Eyes wide, hyperaware of the fact she was on an alien planet with only her panties covering her lower body, Yaz stumbled after it.

Great. It turned out fleeing clothes could be fast.

"Come back!" she said, not raising her voice particularly. Oh god, she didn't want to be overheard, she couldn't be seen like this. She was struggling to keep her shirt on as it was.

And now she was begging her trousers to not run away. To think, once her life hadn't been mind-bogglingly weird.

She stumbled over the ground, praying she wouldn't lose her top, and that she'd catch up to her trousers.
