It very very beautiful, props to the camera men and the editors [who made that tight/awsome/m33p freeze in the dance before the chours...SO awsome!]
It really showed innocence, i LOVED her make up..., the dancing was great but of course, the dancers are

[they've taken LOADS of classes, ballet, jazz, the works].
About those tan line, I think it was intentional, to show that children don't try to look at their best,as adults do, because they would much rather play and dance rather than spend hours in front of a mirror

, the her clevage looked scary too, scarier than the alterna PV
My predictions were correct, I did and do,in fact, enjoy fairyland better after watching the PV [same w/ CAROLS but I didn't expect liking it xD]
