not necessarily, just because you have breasts doesn't mean that you are an adult, it just simply means that you are growing up.
yes, some girls start wearing them when they are 7
I would said ages 9-12 is when they should start wearing bras. It is a personal preference and what there parents think is appropriate.
It is logic for girls to wear cup shaped bras to cope with shape of their breasts.
you should start buying training ones at about really late third grade if needed but most girls start with training bras at really early 4th grade and transition to real bras about 6 weeks after you start wearing training bras and wear it every other day to get used to it.
One cannot determine when to start wearing a real bra by the girls age, it all depends on weather you need it or not, but usually girls start to wearing training bras/ crop tops underneath their shirts when they are 10-12 years of age, then you start to wear a normal bra when you feel that you need one.
I personally think that it is up to how the girls breasts are growing at their age, everyones breasts grow at different ages! I am 11 years old and Im wearing bras. But still girls that are my age have bigger breasts than me. hopethat helped :)
girls wear bras to support their brests. you don't none but most people choose to, it looks best also girls start wearing a training bra when the nipple first starts to show and get larger
Normally when they start the early stages of purberty, which can be as young as 8 (2nd grade) This is when they start developing breast buds. Most start around here with training bras or sports bras. Most start any from 10-12 (4th-6th grade)with normal bras.
Girls don't have to wear bras - many girls do because they feel more comfortable, girls with larger breasts may need the additional support, but no one HAS to wear bras if they don't want to.
8 years old becauuse they are padded
When your breasts start developing you should start wearing crop tops/training bras. Once you have developed large enough to fit into an A cup, you should wear a proper bra.
the age women tend to develope there breast is 12 years old
