Spying through a window, we see a sexy blonde woman in a black nightgown who is upset. She's throwing things off the bureau, knocking over the coat rack and flopping onto the bed in frustration. The phone rings and our beauty has a very deep voice as she answers, "Hello? Yeah, this is Mark."
A female narrator says, "If Clothestime can make Mark look this good, imagine what we can do for a real woman."
Of course, it's the makeup artist that makes Mark look "good" much more than the clothes. The joke here is the age-old "Surprise, it's a man." This spot accompanies two others -- a similar male one and a much more flattering one for lesbians.
