A Democratic congresswoman is calling on her colleagues to "bare arms" and go sleeveless to stand in "solidarity" with reporters who were recently admonished for "inappropriate attire" in the Speaker's Lobby.

Rep. Jackie Speier, D-Calif., is asking her female colleagues to take part in a sleeveless photo-op Friday on the East Capitol steps shortly after the House meets for its first votes.

House Speaker Paul Ryan, R-Wis., has come under fire in the last two weeks after reporters said they were blocked from entering the Speaker's Lobby over their sleeveless blouses or dresses. The dress code, which also bans open-toed shoes, has been in place for years, but became a social media fixation.

Ryan announced Thursday that the dress code enforced in the House chamber and adjoining Speaker's Lobby will be modernized to reflect "acceptable business attire."

The current dress code has even drawn open defiance from members of Ryan's own party. Rep. Martha McSally, R-Ariz., openly broke the dress code on the House floor Wednesday, when she wore a sleeveless dress and open-toed shoes.

First instituted in 1979, the dress code also requires men to wear ties and jackets, but has been sporadically enforced.
