The US Senate has voted to formally impose a dress code, unanimously rejecting a plan to allow lawmakers to wear casual clothing in the chamber.

Members of both parties voted for a resolution establishing a dress code.

Since returning to work in April from treatment for clinical depression, Democratic Senator John Fetterman has consistently sported hoodie sweatshirts and shorts. To stay within the unwritten dress code, he voted from the side of the chamber.

Last week Majority Leader Chuck Schumer ended enforcement of an informal and unwritten code requiring senators wear business attire on the floor.

But the new, revised simple code will require lawmakers to wear “business attire” in the chamber, describing it as a coat, tie and long trousers. It did not address sleeve length or neckline height for women’s clothes, two sources of controversy in recent years..
