Holmes, a 53-year-old Republican from St. John who is chairman of the Senate Ethics and Elections Committee, said he wrote the instruction because provocatively dressed women are a distraction. The guidelines don't detail a minimum skirt length or a permissible neckline for blouses.
"It's one of those things that's hard to define," Holmes said. "Put it out there and let people know we're really looking for you to be addressing the issue rather than trying to distract or bring eyes to yourself."
Holmes said he considered requiring men to wear suits and ties during testimony but decided males didn't need any guidance.
