The blond woman a bit to right of center appears to have a "Bouffant" hairstyle... which (IIRC) was popular with teen girls and women from the latter-1950s into the early 1960s. I was alive back then, and although I was not yet a teenager, I did notice that rather spectacularly tall hairstyle on the girls.
BTW, the car looks like what my Mom was driving in some photos of that time-period.
