How To Look Pretty At The Age Of 11?

Well,...
For Hair You Could Have It Layerd
You Can Straighten Your Hair,Curl It With Curling Tongs, Crimp It..
Get An Adult To Do It If You can't.. :)
Make-Up..
Don't Need a lot For Your Age, You don't Want To Look Too Made Up.
Theres Lip gloss...Mascara. You Could Put On Some Eyeliner?
Eyeshadow...?
Clothes...
Pick out clothes you feel comfortable in..
But you still look good in.
Not much advice I can give you for clothes..
Hope Ive Helped Somehow
Good Luck :)
