A euphamism for fat. Curvy used to describe women who had large breasts, a small waist, and a big, shapely butt.
Now, the media is pressuring young girls and women to look like Scarlett Johansson or Angelina Jolie. If you have naturally small breasts, don't have a tiny waist, or particularly shapely hips, you're labelled as anorexic or "not a real woman". This same media claims to support "loving yourself", but if "yourself" hasn't got a perfect hourglass figure, then you're done for. Hypocrisy knows no bounds, right?
Let's say a girl, named Eve, was a fairly attractive girl. However, as she grew older, she never developed past an A cup. In other words, she wasn't curvy. According to the celebrity-obsessed freaks out there, she wasn't a real woman, so after years of struggling with her self-esteem, she got breast implants.
Because she wasn't a "real woman" without double d's.
