i wish people never thought of the idea of shaving their legs, underarms, 'private' places, arms.. i wish they just let it be! facial hair is understandable though as i can imagine it would get in the way a lot.
I think the first time I shaved my legs was when i was 11, and I was going to camp, and i was taking a skirt to wear at the camp disco lol so i wanted to shave my legs But I used cream hair removal stuff for the first while, you could use that if you want I shaved under my arms even earlier than that but I started going through puberty so early!
I think if she's old enough to decide she wants to shave her legs, she's old enough to do it. I think I was 10 or 11 when I started shaving my legs. I guess I never really understood what the big deal was. Stuff like this is pretty harmless.
