Picture your little one spinning through a living room dance party or feeling like a magical unicorn during a birthday celebration. This Simplicity set is designed to turn everyday play into a full-blown fantasy adventure. The rainbow tulle is layered in separate pieces, which is a thoughtful touch because it allows for easier movement and prevents that stiff, restrictive feeling common in cheaper costumes. We love that the waistband is lined with satin to protect sensitive skin from itching, and the included headband and hair bow ensure the look is complete from head to toe.
