From The Washington Post: Teachers in the Howard County (Md.) school district are being told not to wear inappropriate clothing in the workplace. Last week, the system held a fashion show for 200 new teachers that showed them appropriate -- and inappropriate -- ways to dress in the classroom. This year, for the first time, the school district circulated a pamphlet, "Expectations for Professional Attire," among employees. The guidelines were devised after officials noticed a decline in professional dress among some teachers.
