Well there is one set of clothes available...

Anna mumbled something.

"Anna?" Elsa said.

"'s locked," Anna said, almost as softly, under her breath. She looked down. Elsa eyed her warily.

"Anna," Elsa said again, starting to be worried. "What's locked?"

Elsa squirmed a bit of the spot, trying to keep hiding behind her trembling arms. Mutely, Anna gestured to her wardrobe. Elsa followed her gaze.

Anna's room was as luxurious as one would expect a princess's to be. Her four poster bed, a sofa, a rug, a window with resplendent curtains thankfully drawn that looked over Arendelle, and then in one corner a huge, sturdy wardrobe.

And now the wardrobe notably had an equally sturdy lock fastened over it. Elsa stared.

"Why... why is your wardrobe locked?" Elsa said, turning back around. Then she squeaked. "And close the door! Please!"

Still sleepy, Anna looked around for a moment, before realizing the door to her room was still open, looking out onto the hallway and a passing servant. She waved amiably to them, only for her naked sister to streak past her and kick the door closed so they were out of sight, blushing.

"That was rude," Anna mumbled.

"Anna! Focus!" Elsa said. "Wardrobe!"

"Oh, right, um..." Anna mumbled something else.

Elsa's eyebrows rose expectantly. She kept squirming, disbelieving. Of all the days... Eventually, Anna spoke up.

"So, um, funny story," Anna said. "It's the easiest place in my room to hide things, like, er, presents! For the anniversary, for Kristoff, and everyone, and I don't want people peering in at those, so I thought, best choice, lock it up so only I can get in. Perfect!"

"So... where is the key?" Elsa said, nervous.

Anna mumbled again. She was doing that a lot today.

"Anna! Kind of urgent," Elsa squealed.

"Sven ate it," Anna mumbled.

"What?!"

"I was feeding him a carrot, and it dangled out so he, er..." Anna said.

Elsa stared, cheeks, ironically, flaming. She pulled one arm tighter over her breasts, suddenly feeling the urge all the more to keep them covered.

"So, Elsa," Anna mumbled. "Why are you, er, naked?"

"My dress melted!" Elsa squealed, starting to panic. "It's summer! It's too warm for me to keep one of my dresses on, they keep melting off me!"

Anna stared. A bead of moisture trickled down Elsa's shoulders, a droplet that had once been protecting her modesty dripping down into the valley of her cleavage accentuated by her **** clutching. Anna swallowed.

"Can't you, er, just wear a normal dress?" Anna said.

"I tried! Why do you think I'm here?!" Elsa said.

She didn't mean to shout, she really didn't, it was just hard not to be a little hysterical. She was Queen! Queens weren't meant to be seen like... like this.

"I meant one of yours," Anna said. "Rather than mine."

"I don't have any!" Elsa squealed. "Not any more! All the dresses in the castle are in your wardrobe. Which you... I was talking to the people today and it- they-"

Elsa whimpered. Anna's eyes widened, staring in increasing understanding of her sister's frantic fidgeting.

For a moment she could just picture it. Queen Elsa sat on her throne, her dress turning to water, dripping off of her, leaving her exposed in front of... Anna coughed. And to think all Elsa had been wearing for the past few months was itself little more than water.

Then Anna started pulling her dress off. Elsa stammered.

"Annd, what... what..."

"You can wear it," Anna said, head currently lost somewhere in the garment. "You need it more than me. I'll just- ah! I stay in my room, and you can make the addresses, and... figure something out. Okay?"

Anna wrestled with her dress for a few seconds before finally bringing it up over her head, revealing her newly pink cheeks and a lot more besides.

It wasn't exactly a royal dress, more sleepwear, which meant nothing on underneath and a minimum of finery. Hands shaking, Anna thrust it out, Elsa taking it as demurely as she could before yanking it back to help cover her breasts, arm shaking.

It might well be the only dress in the castle that she could actually wear. A flush spread across her cheeks that mirrored Anna's almost perfectly, Elsa coughed and nodded.

"Thank you," Elsa said.

She slipped into the dress as quickly as she could. At least the simple, no frills nature made it easy to get into. Eventually Elsa straightened, shaking her head to tidy her hair up again, and finally managing to feel comfortable standing a little straighter now she was clothed. Barefoot still, and naked beneath the dress meaning her hard-from-the-cool nipples poked out through the thin fabric, but you couldn't have everything.

Anna meanwhile was the naked one now, smiling hopefully at Elsa even if she was fidgeting now, both arms crossed over her chest more out of instinct than any sensible decision. A triangle of red fuzz went uncovered, until a pointed glance from Elsa made her squeak, flushing, and remember to spare a hand for that too.

"So, er, you can ask Kristoff to bring dresses up from the village right?" Anna said.

"Certainly," Elsa said. "I'll just... apologize for how poorly my audience went, and make amends if I can. We... we never talk of this."

The red-cheeked Anna nodded frantically, before hurrying into her bed and pulling the sheets up to her neck, squirming a little.

Doing her best to keep acting confident, Elsa turned and walked out the door. She straightened as soon as she was in the hallway.

She was the Queen. She had to act like the Queen. No shame, no nerves. Deep breaths.

She glanced down, feeling damp seep into the dress. Ugh, she was still wet from when the ice had melted. Barely thinking about it, she created a layer of frost to suck out the moisture. It'd melt, but at leaast it wouldn't expose her when it melted, it couldn't go much worse.

Professionally, Elsa walked, trying to find her way back to the meeting hall. If she'd been in a better state of mind though, she'd have remembered that when water froze, it expanded, which meant her idle freezing wasn't the best idea for the integrity of her dress. Already the sizeable patches she'd frozen to keep from the damp bothering her were looking a little frayed.

Clad in the last dress in the castle, and idly freezing again as a patch got damp faster, Elsa began to return to the site of her exposure.
