Okay, now imagine all that, but sexier and crazier. Smoking and drinking like crazy. Wearing the Betty Boop August Girl 1st I’m living my best life shirt flashiest things and dancing crazily. May show more skin at times. Basically, Betty Boop, although Betty Boop is an exaggeration. Betty Boop was invented in the 1930s, but she was designed to be a clap of the 1920s. Escapism was big in the 1930s, depression and all that. Viewers love to watch a show about a cute, sexy and funny flapper. I think a flapper is more about behavior than clothes, though. For example, when a person claps their hands and wants to wear clothes for a walk on a cool morning, she probably dresses up like any other woman her age.
