I recently went to visit a friend at her very conservative and upscale law office on a Friday, and witnessed (gasp!) some employee versions of Causal Friday or being comfortable. One employee decided that pajamas were acceptable and passed for Casual Friday attire (he was too comfortable).. Another employee decided that less was more, so she wore a denim skirt with very little denim (or any other material). Perhaps when some hear the words "Casual Friday," all inhibitions go out of the window.
Casual Friday became popular during the dot.com boom of the 1990's where the relaxed atmosphere of California-based businesses thought that at least one day of the week their employees could relax from the more "dressed up" attire of the other four days of the week. As far back as 1947, Honolulu-based companies started a trend in which employees could wear Aloha shirts on Fridays.
The idea has good intentions; relaxing the dress code on a Friday seems like a nice idea, but Causal Friday should be just that and not an invitation to take being comfortable a little too literally. After all, it is still the office. Let me know your thoughts. Bon Vendredi!
