I wear bourbon and walnut Strands anyway, but I'm in an education setting. Up until a month or two ago, we had no official dress code. I had done a school hoodie and jeans on Friday before with no batting of eyes. Some coworkers wore t-shirts and sweatpants (dead serious). We now have a business casual policy with a denim ban unless it's Friday and you don't have any appointments with other departments, students, or the general public.
