Lucy is wearing an old-fashioned hoop-skirt, with frilly leggings underneath that are held up by a fabric belt tied in front. She and Ethel are performing their audition act for Ricky at his nightclub. During one turn in their dance, when her back is to us, Lucy clearly looks down to find, and untie, the belt that's keeping her leggings up. As she continues to dance, they fall to the floor, as if spontaneously and by surprise.
