Allowing senators to wear what they please on the Senate floor may seem like liberation, but abandoning the dress code could wind up symbolizing the failure to achieve consensus.
Some senators worry that more casual dress might breed disrespect for Congress. Others argue that the harshest critics have already debased the institution, even in business attire.
Senator Chuck Schumer, the majority leader, will no longer enforce the informal dress code for the chamber, which for decades has dictated that members wear business attire.
