I remember it clearly. I was a sophomore in college when one of the girls in my a cappella group stood in front of the classroom we were practicing in and gave us a crash course in posing for photos, so we always looked our “best,” which basically meant skinnier. Snatched, if you will.
She turned to one side, pushed out her chest slightly arching her back and, then, the pièce de résistance: She perched one arm against her hip. She called this pose “The S Curve,” alluding to the curved shape it created. (Unrelated, but this girl also gave us a signed copy of her own home-recorded CD for Christmas one year. Ah, to have her unbridled confidence...)
