Different girls develop at different rates, so there is no “normal.” Some of the girls in your class may be more developed than you, and so their breasts look like adult women’s breasts, whereas yours have not fully developed yet.

Different women and girl’s breasts also look different. Not only do the size and shape of breasts differ, but so does the size, shape and color of the nipples and areola.

For more information on how different breasts can be, check out Teen Talk on Planned Parenthood’s Web site.
