The Vũ đoàn Number One troupe of Ho Chi Minh City (Saigon for us old timers) performs in some unusual costumes - their skirts are split, but worn with the split in the back. Two-tone knickers. Posted for its novelty.

The Facebook page does not have any photos of the cancan, but they do post a fair number of performance photos, so if the video was recently filmed, then some may show up later.
