It's the much loved Cottage Mama Party Dress pattern! White satin with a rainbow organza over layer.
Obviously Princess Dresses are for doing 'Ballet Spins' in!
It has a rainbow ribbon at the waist (declared Lizard's favourite bit) and silver ribbon at the neck and the hem.
It's also for an iron on rainbow applique which is on a blue heart purely so I didn't ruin the organza with over heating it under the iron.
