My current 12-year-old's experience: in 4th and 5th grade (elementary school), mostly the girls with breast development. In 6th grade (middle school), every girl.
Which actually parallels my experience in 1980, except that the transition from some girls to all girls was in 7th grade, because that's when junior high school started.
Also, "sports bras" don't do a thing for the tenderness of breast buds. They are a layer of knit cotton, not armor.
This exactly. It's not until the girls have to start changing for gym that most girls wear something. Otherwise, just the ones that need it.
