I was made to start shaving at around 11, but stopped completely at around 14. It was risky in P.E (Physical education, or gym class) at school, but thankfully our P.E school uniform though it consisted of shorts, also included knee high football socks. The same for both sexes. So noone saw my hairy calves, though some people would comment on the slight hair on my knees.
I remember one day, I forgot my socks. I was freaking out, as I would have to do P.E without and everyone would see my legs and Id get done for forgetting part of my P.E kit. My twin sister stepped in and let me use her socks, she saved me so badly and I was so thankful!
Also, around 15 I started wearing bandages to flatten my chest. Though after being forced to wear a (hate the word) bra, at 11, I never did after age 12.
