Calling all moms of girls!

I am trying to find out what measurements to make my tutus for the different sizes. I can't really go by Gloria's size (the 19.5" one worked best for her) because she is supposed to be wearing a 21-22" waist in a tutu right now and she isn't. So...as a general thing can you moms measure the waists of your little ladies and post the inches on here? Thanks! I appreciate it!
