I work for a small Internet company in downtown Vancouver.
We don't have an office dress code, and rarely have any customers visit. As a result, I could wear pajamas to work every day.
Most of the people here work on the technical side and wear shorts/jeans and t-shirts year-round.
As we're in downtown Vancouver in the financial district, many of the office workers in our building and the immediate area wear suits and/or business casual.
I usually wear a dress shirt...
