  • Disney Ursula: Size labels include 5-6 Years and 7-8 Years. Check the individual measurements and current options on the product page.
  • Disney Princess Ariel: Includes Dress only in the currently listed under-three size; headband not included.

Plan the character and finishing details

Coordinate colours and any separate headwear with the outfit. Check the contents before adding accessories, particularly where the costume already has decorative details of its own.

Choosing the fit for Little Mermaid costumes

Choose Little Mermaid costumes using the individual product’s measurements and the clothing you plan to wear underneath. Before completing the outfit, compare the included-item list with the photograph: footwear, hair styling and handheld props may be separate choices.
