Looking after your appearance may not be explicitly stated in your job description, but it's an expectation. Coffee spills and stockings run. It happens, it's pardonable and you can blot the stain or change clothes, then get back to work without raising any eyebrows. But sweat stains? Week-old soup splatter? Wrinkles and missing buttons? Unforgivable! Our clothes keep us warm, make us look good and cover up our naughty bits in situations where our naughty bits need covering. They take care of us, so take care of them.
