Cloverfield (2008)

While a woman sleeps, a man videotapes her (we see her bare back, shoulders and one leg to the upper thigh) and we see the young man bare-chested and wearing boxer shorts when she turns the camera on him (it is implied that they had sex the night before).

While climbing across a rooftop the wind blows a woman's skirt up and part of her underwear and upper thigh is briefly visible.

Young women wear low-cut tops and dresses that reveal cleavage and bare shoulders in several scenes.
