They were going to a party. It was an extravagant party on some unpronounceable planet, requiring very formal outfits. Rose had gone all out, raiding the wardrobe until she had found the perfect dress, a forest green one, not unlike the dress she had worn when they met Charles Dickens. The Doctor watched, amused, as she went through the shoes, occasionally commenting on where he had acquired them. It was all entertaining until she had set her eyes on him.
"Oh, you can't go like that!" she complained, looking distastefully at his normal brown pinstriped suit.
He glanced down on it. "What's wrong with this suit? I like this suit!"
She grinned, shaking her head softly. "It's no fun if you're not dressed up." She circled around him. "C'mon. I found a tuxedo in the wardrobe room. You can wear that." Turning, Rose headed out of the console room.
Scowling, the Doctor followed.

After two hours, five suckers, and a promise to make him a banana milkshake, Rose had finally gotten him into the black tux. He had complained the whole time.
"And the bow ties! I hate bow ties! They remind me of old professors or something." He continued his rant.
Rose adjusted the item of clothing in question, musing quietly. "I like bow ties."
This statement caused him to (miraculously) stop talking. "You…like bow ties?" he asked, confused.
She gave him a sweet smile. "Yeah. I think they're cool. Plus you look good in it."
He was taken aback by that. Then, a slow smile spread across his face.
"Now, are you ready? Let's go."
He swaggered out of the TARDIS doors, feeling much more confident.
Rose just sighed. "Just what he needs, a bigger ego."
