1940s beauty queens

Sarasota Sun-Debs from 1949 learning how to elegantly pick things up off the floor at Lido Beach, Florida. Which one of these two are doing it correctly? I’m guessing it’s the girl who’s got her knees bent rather than the one bending down with her bottom at perfect pinching level! Does anyone know what a Sun-Deb is? Are they beauty queens, or debutants in bikinis?
