The age at which girls develop curves varies greatly, as it's a part of puberty which occurs at different times for each individual. Generally, girls start developing curves between the ages of 8 and 13, and continue to develop their figure until they are about 18 to 20 years old.
It's important to remember that everyone is unique and there is no one-size-fits-all answer. Some girls may notice curves earlier or later than others, and everyone develops at their own pace.
