Left out a little tidbit about the dress code at work. To put it simply, there isn't one. Jeans are standard. Tennis shoes are typical. And hoodies are necessary (subzero studio temperatures, you see).
But prior to stepping foot in the office and unprivvy to this information, my interpretation of business casual was... more business, less casual. Because I opted for something a little snazzier, I got a lot of this -- "You know how I know it's your first day?" And this -- "Bet you won't dress like that tomorrow, will you?"
To that, dear co-workers, I have a reply. I might lose the dress, maybe even the blazer... but the heels? The heels are here to stay.
