Taekwondo for my girl

My 5 year old daughter asked us she if she could learn Taekwondo.  Maybe to defend herself if her brother attacks?  :)  You may remember the shirt I made for him.

She told me she needed a shirt to wear under her uniform.  For some reason, I saved the freezer paper 'kick person' from my son's shirt and used it.  I decided to use her favorite color.
