I loved Esther Williams movies! I spent many a happy Saturday matinée at the movie theater watching them when I was a kid, and a pre-teen and a young teen. Apart from the swimming extravaganzas, I remember musicals, and light romantic comedies, and just plain enjoyable movies with top-notch casts in addition to Williams.

Perhaps her movies appealed more to females, I always saw them with my girlfriends. In those days, theaters still had very large screens and her movies were always bright and colorful, and, I guess, what would be considered "wholesome" entertainment. And she was a fairly good actress, certainly for the kind of films she made. I associate her with happy childhood memories of my movie going.
I also remember her line of swimsuits. I never bought one, but they seemed like well made suits.
