Hand-selected by practitioners for quality and energetic resonance.

Rise from moonlit waters in the Siren’s Moon Mermaid Gown, a floor length fantasy costume made for nights of enchantment. Light catching shimmering details ripple across a soft polyester blend as you move.

The Song of the Siren

In sea lore, sirens and mermaids are traditionally associated with allure, mystery and the wild pull of the tide. Many sea witches honour that energy through costume, ritual and a little sea witch style.

Why you'll love it

  • Moonlight shimmer: The details catch party lights and candlelight with every turn.
  • Full length drama: The long silhouette creates an instantly recognisable mermaid shape.
  • Room to move: The wearable design lets you dance, walk and pose freely.

A Gown that Shimmers Like the Tide

The full length silhouette flows to the floor while the shimmer plays like moonlight on water. Add pearls and shells for a soft siren, or dark makeup and crystals for a sea witch.
