However, this was dropped in both the strip and the specials by 1969, possibly so it would be easier to draw or animate. She wears a polka dot dress with a small bow in the back. Her dress is colored light blue in all thirty-seven TV specials, the TV series The Charlie Brown and Snoopy Show and This Is America, Charlie Brown and the movies A Boy Named Charlie Brown, Snoopy, Come Home, Race for Your Life, Charlie Brown and Bon Voyage, Charlie Brown (And Don't Come Back!!). Her dress is, however, usually colored pink in the Sunday strips and appears in that color in The Peanuts Movie and the 2014 French TV series Peanuts onward. In the later years of the strips, Sally is often seen wearing a sleeveless or long-sleeved polka dot shirt and pants. It is also revealed in the Novemcomic strip Her outside winter outfit is a jacket to match with her dress (although she is sometimes seen wearing a hat). That Sally wears a retainer, meaning she possibly has dental trouble. For swimming and going to the beach, Sally wears a bikini swimsuit. For bedtime and nighttime, Sally wears a nightgown. Sally stands for all the frustration and confusion that little kids experience at school. She is a favorite of many people because she is so uninhibited.

The school building comforts Sally in the strip from October 24, 1974. Sally has a "take it easy" approach to life, preferring to slide by while doing as little work as possible. Her favorite pastime is sitting in her beanbag chair watching TV. In a series of strips from June 1982, Sally even goes to "beanbag camp" for the summer, which consists of nothing but lazing around in beanbags, eating snack foods and watching TV. Sally gets fat as a result and needs to exercise when she comes back from camp in order to lose weight. Like her older brother, Sally has a good heart and a strong moral sense.

She is extremely sensitive to the unfairness of life.
