Serena and Venus Williams have reunited on tour once again—and the sister jokes are as plentiful as ever. Little sister Serena had some comments about Venus' attire (or lack thereof).

"Why are you wearing a T-shirt to the event?" Serena asks Venus.

The sisters were attending a team dinner ahead of the U.S. Fed Cup tie against The Netherlands in Asheville, N.C.

It's not the first time Serena has made fun of Venus' penchant for wearing short skirts.

The U.S. would advance to the semifinals with a 3-1 victory over the Dutch team. Serena and Venus Williams thrilled fans by uniting on the doubles court (though they would lose the match).
