A/N: This one was just fun to write. I love it when Beckett actually acts like a girl. Enjoy (please review).
Standing in front of her closet, Kat couldn't for the life of her remember why she had agreed to this. Not only did she not want to have to parade around all night like she was Castle's girlfriend, but she truly had absolutely nothing to wear. It was one thing, putting on a sexy dress to surprise him at a book signing it was an entirely different thing to find one fitting of a black tie event.
At least Lanie was there to help with her total girl moment. Because Kate Beckett did not have girl moments like this, not anymore. Sure she went on dates every once in a while, but nothing that made her this nervous. Why was this making her nervous? It was just a little undercover work, not a big deal. And definitely not a date. But it was Castle, and he would make it a big deal. Why had she agreed to this?
"You know what he's trying to do? He wants to humiliate me." Well, that probably wasn't entirely fair. What he probably wanted was to see her in a tight dress again, but she wasn't thinking about that. The doorbell rang. What now?
"Lanie can you get that please?"
"Alright, but you better not be wearing your prom dress when I get back." Lanie thought it was funny, but as Kate stood in front of her closet again, she thought that might not be far off.
"Bibbodi, bobbidi, boo?" Oh, hell no.
"Cinderella. It's from him." Of course he would know she had nothing to wear. This was a disaster.
"Oh please, it's a dress." But it was from him. "Now open it up girlfriend."
"Oh, I knew he was arrogant, but this, this is complet- Oh." Well, shit. The dress was… gorgeous. Revealing, of course, but classy and elegant and, oh hell, this was going to be torture. She wanted to ignore it out of spite, just so she wouldn't have to see his smug smile when he saw her in it. But damn it, you couldn't just ignore a dress like this.
Martha opened the door long before Kate was ready, but she tried to smile through her insecurity.
"Stunning, simply stunning. Come in, come in. Oh, hang on." Martha rushed out of the room as Castle and Alexis entered.
And there it was, Castle's smug smile, thought he wasn't gloating quite as much as she was expecting.
"You look incredible," came Alexis' greeting. A wave of relief mingled with Kate's anxiety.
"Really?" Oh, why did she have to be such a girl?
"Really. You clean up nice Detective Beckett." Castle said as he looked at her approvingly, only a hint of his smugness still visible under the sincerity. And now she was blushing, fantastic. This was going to be a long night.
