McCall'sM7000 Women and Girl's Fairy Tale Snow Princess Costume Sewing Pattern, Sizes 3-14

DOES THIS INCLUDE KIDS SIZE 14

I want to make an Elsa dress for my 7 year old, is this an easy pattern?

Where can I take a look at the sewing instructions for this?

Are there adult sizes in this too? The main picture shows and adult anna and elsa. I wear an adult medium (size 8).
