Guess my mom was ahead of her time. I started kindergarten in 1949, and my mom sewed all of my little dresses......... I WAS a little girl, after all. But, she also made a pair of "panties" that matched the dress material. I would wear them over my normal underwear........... then I could hang from the monkey bars, swing on the swings, and climb up the jungle-gym, and no one could see anything they weren't supposed to see.
