Crossdressing at costume party

[jessica_brink]

Hi, a couple of my friends are throwing a costume party, and the theme is Big Bang Theory (the comedy tv show). I was thinking of dressing up as Penny (the hot blond chick), but I’m not sure if I should. No one knows I dress, and I don’t want to come out or raise suspicions. What do you suggest I do?

Secondly, should I go as Penny, what should I put on to make me look like her? What would be the most fitting outfit (what type of clothes, hair style, cup size,…)? I am familiar with the show, but it’s really hard to choose a good outfit, since she has so many clothes and hair styles to choose from. If you could give me some suggestions here or put some links to some of her outfits, that’d be really helpful! X

Edit: one more question, should I also wear lingerie underneath, even though no one there will get to see it?

Update: Thanks for all your advice, after reading your comments and thinking it through, I've decided to do it! I just have to make sure I play it off as a joke, don't take it too seriously. I've been looking at lots if outfits, but in the end I' ve come up with this one: https://s-media-cache-ak0.pinimg.com...985ad3f122.jpg I also looove her hairstyle here so I'll probably go with that one as well. Now I need to find a matching wig and dress, so if you see something that looks similar, please let me know.

Also, I still haven't decided on whether or not I should lingerie, any advice on that?

Update 2: Unfortunately something happened to the organizer of the party who's also a good friend. I'm not going to say what exactly as it's quite personal, but because of it the party has been delayed, hopefully not cancelled. I'd say it'll happen around November-December. I know I probably come across as a faker now and I don't blame you, but this is really what happened. I just prefer not to go into detail about it as like I said, it's a personal matter. On the bright side, this does give us some extra time to discuss the outfit. I'm still really unsure about the lingerie: should I, what pieces and size, and where should I get it from?
