Layne and her on-screen husband, Ari'el Stachel were also on-set for the final scene in Victory, just before Alice floors it across the desert for the car-chase.

Margaret does not wear this costume at any point in the film (it is similar to her costume from Frank's BBQ, but that has spaghetti straps). Layne *did* wear it for her EPK interview & it was also included in her post about most of her scenes ending up on the cutting room floor.
