A princess and her peticoats

"I think I'll only wear one of my princess skirts today."  Said no toddler ever.  Why wear one princess skirt when you can wear four?  For reference, the fourth skirt is hiding just below the third (we only have so much torso to work with); the necklace is referred to as an amulet (and is a nod to Sophia the first); and the shoes she's wearing are her glass slippers.  Got it?  No?  Don't worry, you'll be swiftly corrected.
