In the summer, boys dress for the warm weather, but girls dress hardly at all.
Most high school guys are in baggy shorts, while many of the girls are wearing shorts so short that parts of their rear end remain exposed.
The “distressed” versions — with rips and ragged hems — are often called Daisy Dukes, after a sexy character who wore them in “The Dukes of Hazzard” TV series (backstory to follow). They’re not a great look even beside a swimming pool, but girls are wearing them on downtown streets.
No matter how fine the girl’s character or perfect her figure, the effect is trashy, hollering sexual availability. That the boys checking out the half-naked girls are themselves well covered confers on them superior status. (Do note that I am writing from a heterosexual point of view.)
Britney Spears recently sent the celebrity media atwitter with an Instagram offering of herself in half-unzipped Daisy Dukes and nothing on top, though her hands were strategically placed. Not doing the latter could have gotten her thrown off the social media app.
