In this hard-to-follow storyline, a woman and man undress and have passionate sex.
The next day, the man wakes before the woman, puts on her white T-shirt and goes out. She then wakes too and goes out, wearing another shirt. As she returns, she passes another woman on the stairs who looks a lot like herself, wearing the same white T-shirt she was missing.
Then in a bar, the second woman grabs the first and suddenly they are at her apartment. They start to get passionate together. The first woman strips the T-shirt from the other and puts it on, gives her a kiss, then storms out the door. The second woman, covering her breasts, runs after her to see her leave.
The tagline: "No one can rip off the original."
It's not clear if the first woman in this commercial was just manipulating the second to get the shirt or if she was into the affair. She did give her a kiss after she got the shirt back, so it implies some interest there.
This is a rare example The Commercial Closet has of bisexuality--which is downright invisible in advertising. It is also a rare case where even though the women appear to be bisexual, they are not present for the male gaze in the commercial.
