All tutus for people are sizeable several inches to make them bigger or smaller.  When you make a tutu smaller, it gets fuller and when you make it bigger, it gets less full.  If you need a custom size/length, I will calculate cost.  If you want a Hybrid tutu, ex: Classic length, Whimsical style, price will be that of a Classic tutu.  Since I use a formula to calculate cost, the varying factors are waist size and length.
All pet tutus have a 2-4 inch gap on the waist where there is no tulle.  This is to ensure the tutu stays clean from pet's normal potty breaks.
