I have friends with age ranging from 11-30, and one of my friends (who is 11) went out with her friends to go to the mall. Now you'd expect that going to the mall you'd wear something casual, but she told me what her friends wore were jean booty shorts (that basically covered as much as cheeky underwear does), crop tops that go only a little below their chest, high heels and a full face of makeup. She also said that they always wear padding for their butt and boobs when they go out, but not at school since she notices the major differences, and apparently they plan to buy waist trainers as well from the conversations they've been having.
