Two character designs done for a play of the tabletop game, City of Mist, Gina (the first, the mother) being the player character and her daughter, Lillian, serves more as a MacGuffin to eventually find. As the game is set in the 1950s, both characters are dressed in the full skirted dresses we'd expect of the era, in contrasting colours.
The red and white were chosen due to the Red and White chessmen in Alice Through the Looking Glass, as Gina's power set and design are inspired by the White Queen, and Lillian was later designed to contrast that.
