This is a skirt only, it is NOT skirted bummies. These do not have anything underneath the skirt.
This skirt is made of pleather stretch fabric. See size chart in picture to ensure you get the correct size skirt.
Pleather fabric does not stretch as much as regular fabric. We recommmend that you SIZE UP for these skirt. Example: if the size chart says you would need a 3T for your child, buy a 4T in all pleather fabrics!
