and the winner was...

Thanks for the help! So this is what I finally went with... the navy jacket and I added a gray sweater since I can't seem to go anywhere with less than 3 layers. (It's sad but true!)

Overall, it went over quite well... tho my co-workers stuck to basics (boring!). ince many of other attendees got all dressed up I didn't feel too out of place. And I must say, there were a number of bow ties there that night.... but mine was the biggest.
