Thanks for the comments, ladies.
Ameli, although many people I work with were invited to the costume party there were a lot of no-shows. I only knew 6 people there.
As far as what they might have assumed, it's impossible to ever know what people are privately thinking. All I know is that everyone was having a good time and there were no rude comments. Obviously there were some good natured jokes throughout the evening and I was referred to as "one of the girls" several times.
In my heart of hearts I truly believe that my outfit was interpreted as a one-time only event. My reasoning is that when I arrived, I was wearing my (male) winter topcoat and boots. If I was wearing a woman's coat and high heels that might have raised some eyebrows. As is the custom in Canada, everyone takes their shoes off when entering a home so I wasn't in a situation where I would be scrutinized as to my efficacy of navigating in heels.
Another reason that I feel I flew under the radar (Stewardess pun intended) is that my makeup consisted of nothing other than eye shadow and lipstick. My legs weren't shaved and I didn't affect feminine mannerisms.
Having said that, perhaps I inadvertently gave away some clues. I was clearly enjoying my time, blushed at every mention of being "one of the girls", and I talked waaaaay too much about pantyhose!!! In addition, I received so much positive attention that I undid a couple of buttons to really show off my lacy bra.
At the end of the day, people will draw their own conclusions. But the bottom line is that I had a fantastic time and everyone seemed to be having fun themselves.
