Interesting when you mention male senators being titillated by a bare female arm to the point of fondling themselves, you failed to mention the proposed dress code bill was introduced by a woman and supported by other female legislators.
From the article you referenced -
Rep. Ann Kelley, R-Lamar, proposed explicitly requiring women legislators to wear jackets on the House floor, saying “it is essential to always maintain a formal and professional atmosphere.”
Rep. Brenda Shields, R-St. Joseph, said Kelley’s plan was intended to clarify current rules because the previous wording left the dress code up to interpretation.
