Help Needed!

I was invited by Saks Fifth Avenue Chicago to attend a private media event Thursday morning for the unveiling of their new shoe department and to meet shoe god Brian Atwood. Then that evening I'm also invited to their big Fashion's Night Out event. Which leads to the most important question of the week: WHAT AM I GOING TO WEAR????????

I so far have picked out my foot attire. Since they are the most recently purchased and this season, I'm going with the Valentinos.
But what to wear on top???! I just picked up some adorable black skinny pants from Club Monaco (darn them and their lack of online shopping, so I can't post a pic), which I think would be cute with the heels. *GASP* I know, I'm contemplating wearing pants. What has become of me?

I need your help coming up with possible outfits. Mr. EWP has somehow agreed that I need a new outfit to meet Brian Atwood (I'm not sure what he was smoking at the time, but it'd be nice if he continued to do so). Since this event is in just two days, I don't have time to deal with online purchases and must work with what I can get to around my 'hood. So come up with options that I can pick up at: Scoop, Intermix, Nanette Lepore, Club Monaco, Cynthia Rowley, Marc Jacobs, or any of the many cute boutiques in Bucktown. HELP! HELP!

Please post links to actual pieces or ideas for the outfit in the comments or send me an email.

Possible prize for any suggestions I end up using.

Thanks!
xoxo,
EWP
