Dana went out of the dressing room for the tenth time. John and Sherlock were sitting in front of it. John tried to give an honest opinion about each of the dresses, while Sherlock just stared at the other girls in the store. He was deducing them, obviously. He couldn't just sit there and let his brain rest.

"So, how do I look?" she asked once more.

Truth to be told, John thought, she was beautiful. Particularly in this dress. It was tight in the upper part of her body, and was more loose from her thighs.

"This one. Definitely this one."

"Dr. Watson, you said the same thing about the previous dress. And the one before it."

"No, this one is definitely the prettiest." John hoped this would help her finally pick a dress so they can leave. Dana smoothed her dress and looked at herself in the mirror.

"What do you think, Mr. Holmes?" she asked, still looking at her reflection. He looked at her briefly and then looked away again.

"This one doesn't fatten your hips like the blue one did."

"Sherlock…" John castigated him. He thought she might be offended by this supposedly-compliment.

"That's what I thought. Glad to see I'm not the only one who noticed that." she looked at her reflection with satisfaction. "I think I'll go for this one."

"Oh, that's great. So you go change and I'll put all those dresses back." John said, relieved that they can finally leave. He quickly picked up all the dresses and left. Dana went in to change.

"Mr. Holmes, can you unzip me, please? I'm afraid I can't reach it."

He reluctantly got up and went in to her changing cell. He put his left hand on her back and she shivered.

"Anything wrong?"

"Your hands are cold."

"Oh. Sorry about that."

He took the zipper with his right hand and pulled it down. He did it slowly, for some reason.

"Done."

"Thank you, Mr. Holmes."

He stood there, still looking at her back.

"Now, do you mind stepping outside so I can change?"

"Oh, yes. Sorry."

He walked stiffly out. John was surprised to see him coming out of there. He gave Sherlock a confused look.

"She asked me to unzip her."

"That's what I thought."

She got out, dressed up, with the dress in her hand.

"Done. Now we just need to pay for it. Don't dory, Dr. Watson, Mycroft gave me his wallet. You don't have to pay a pound on it."

"Oh, good."

They paid for the dress, far too much in John's opinion, and they separated – Dana went to Mycroft's office to return him his wallet, and the men went to the apartment. Just as John closed the door behind him, he received a text:

In case you didn't understand yet, this is me officially inviting you to the wedding. Wear something nice.

"Sherlock?"

"Yes?"

"Do you have a suit?"
