Hmm… not really a fair test, since ‘plain’ Carolyn ACTED differently to ‘sexy’ Carolyn as well as looking different.
You may have already seen this video, in which Caroline, an attractive young journalist, hits central London in two different get ups and observes how people - “people” in this case meaning “presumably heterosexual men” - respond to her.
In one set of scenes, she asks for free bus rides, taxis, ice creams and drinks dressed in a long skirt and long-sleeved top, hair tied back with no make-up on. In the other, she attempts the same wearing a short dress, curled hair and make-up.
You can probably guess the results without watching the video. “Sexy” Caroline gets everything she asks for and more. “Plain” Caroline gets turned away every time.
