Susie Carmichael - Rugrats
Depending on the length of your hair, you can either do Susie from Rugrats or Susie from All Grown Up!
Hilary Banks - Fresh Prince of Bel-Air
Don't let the looser curls keep you from trying this one. You can achieve a similar look with a bantu knot out.
Tia Landry or Tamera Campbell - Sister Sister
Another one with looser curls, but again, a similar look can be achieved with a twist out.
Valerie - Josie and the Pussycats
This one is perfect for the ladies with a twa.
Gerald Johanssen - Hey Arnold
Can't forget the guys. You may need to buy a wig and sculpt it to get that "tower."
