Ursula Costume Guide The Little Mermaid · Disney · Sea Witch

The most theatrical Disney villain — commanding, glamorous, and wickedly unforgettable. Everything you need to transform into the Sea Witch this Halloween.

Quick Answer: To dress as Ursula you need eight pieces: a black Ursula costume, a short spiky white wig, drop seashell earrings, a snail shell necklace, strappy gladiator pumps, red lipstick, red nail polish, and purple face & body paint. The purple body paint is the key transformation element — without it the look reads as a generic black dress rather than the Sea Witch.

Ursula is the iconic antagonist of Disney’s 1989 animated film The Little Mermaid — a cecaelia (half human, half octopus) who was banished from King Triton’s palace and now strikes deals with desperate merfolk from her lair in the deep. Voiced by Pat Carroll, Ursula is a masterclass in theatrical villainy: lavender skin, short spiky white hair, bold red lips, aqua eyeshadow, and an operatic presence that commands every scene. She is consistently ranked among Disney’s greatest villains and remains one of the most recognisable and beloved Halloween costume choices.

How to Style the Ursula Costume

Body Paint Application

Apply purple body paint in multiple thin coats rather than one heavy application. Set each layer with translucent setting powder before adding the next — this dramatically improves longevity. Apply to the face last to avoid smearing while putting on the costume.

Spike the Wig Before You Leave

Style and spike the white wig before putting it on, using hairspray or wig-specific gel. Once it’s on your head, the spikes are difficult to adjust. Allow the product to fully dry before leaving — this gives you Ursula’s distinctive silhouette from the moment you arrive.

Ursula’s Voice & Presence

Ursula commands every room she enters. Speak in a deep, theatrical tone with deliberate pacing. Use grand arm gestures and move slowly and purposefully. Her sinister laughter — a full, wicked cackle — is the single most effective in-character performance choice at any Halloween event.

Nails Are a Detail That Reads

Red nails are a finishing detail that communicates Ursula’s precise, glamorous self-presentation at close range. Apply the nail polish two days before the event so it is fully set, and bring a small bottle for touch-ups. Ursula’s nails are always immaculate — chipped polish undermines the character’s attention to her own appearance.

Ursula Group & Couple Costume Ideas

Most Iconic Duo

Ursula & Ariel

The Sea Witch and the Little Mermaid — the most immediately recognisable pairing from the film. Ursula’s lavender theatrical glamour against Ariel’s red hair, shell bra, and green tail creates an unforgettable visual contrast that generates instant recognition from anyone who has seen the film. The power dynamic between the two characters gives the pairing theatrical energy throughout the event.

The Little Mermaid Ensemble

Ursula alongside Ariel, Prince Eric, King Triton, Sebastian, and Flounder — the complete Little Mermaid world. As the villain of the ensemble, Ursula’s theatrical presence anchors the group’s dramatic stakes and generates the strongest reactions. The contrast between her dark glamour and the brighter, warmer aesthetics of the other characters makes the group immediately readable as a complete Little Mermaid cast.

Villain Duo

Ursula & Maleficent

Two of Disney’s most theatrical and visually commanding villains sharing the same event — Ursula’s lavender glamour and nautical drama against Maleficent’s angular dark robes and horned silhouette. Both characters are defined by their theatrical self-presentation, their commanding physical presence, and their wicked intelligence. A pairing that communicates Disney villainy at its absolute peak.

Ursula, Cruella & Evil Queen

Three of Disney animation’s most iconic female antagonists in a single ensemble — Ursula’s lavender sea-witch drama, Cruella de Vil’s black-and-white fur coat maximalism, and the Evil Queen’s regal gothic severity. Three completely different visual registers that share the common thread of theatrical self-possession and wicked intelligence. One of the most recognisable Disney Halloween group concepts available.

DIY vs. Store-Bought — Ursula Costume

Store-Bought Build

The most straightforward Ursula build uses the official Disney prestige costume as the foundation — it captures the silhouette, colour, and detailing without requiring any construction work. Add the white spiky wig, seashell accessories, gladiator pumps, and makeup. The purple body paint is the only element that requires any skill or preparation time, and it is a widely available theatrical makeup product. Total cost for a store-bought build typically runs $60–$120 depending on the quality of each item.

  • Ursula costume = the essential anchor piece; buy rather than make
  • White spiky wig = widely available; essential for character recognition
  • Accessories = inexpensive additions that complete the look
  • Purple body paint = the preparation element; allow 30–45 minutes

DIY Build Strategy

A DIY Ursula build replaces the licensed costume with a black dress you source or already own, focusing budget on the accessories and makeup that communicate the character most specifically. Choose a black dress with dramatic volume at the hem — a maxi dress with a ruffled or layered skirt reads as Ursula’s tentacle silhouette more effectively than a simple sheath. Pair with a deep purple or black petticoat underneath to add volume. The white spiky wig, seashell accessories, and purple body paint remain essential regardless of the dress choice.

  • Black dress with volume = check wardrobe first; maxi or ruffled hem preferred
  • Purple petticoat underneath = adds tentacle volume inexpensively
  • DIY total: $30–$60 if dress is already owned; $50–$80 if sourced
  • Recognition key: the wig and body paint carry the character — don’t skip either

Ursula Costume — Frequently Asked Questions

Ursula wears a dramatic black strapless gown, a short spiky white wig, drop seashell earrings, a snail shell necklace, strappy gladiator pumps, bold red lipstick, and red nails. Her skin is lavender, achieved in costume with purple face and body paint, and her eye makeup features aqua blue eyeshadow with thick winged black liner and false lashes.

Apply purple face and body paint as a base across all exposed skin. Build coverage in thin layers, setting each with translucent powder. Add aqua blue eyeshadow across the lid, thick black winged liner, and false lashes. Apply deep red lipstick last. Paint nails red in advance. Contouring under the cheekbones and along the nose adds the dramatic depth Ursula’s face is known for.

Ursula has a short, white, spiky wig — cropped close to the head with sharp upward spikes. Use hairspray or wig-specific gel to hold the spikes firm and upright throughout the event. Style and set the wig before putting it on for best results.

Ursula wears strappy gladiator pumps — bold, high heels with a gladiator strap design in black or dark purple. The gladiator style adds theatrical height and commanding presence that suits the character’s energy. For extended wear, black platform sandals in a bold style are a practical alternative.

Yes — the Ursula costume is one of the more accessible Disney villain builds. The core look uses eight pieces, all of which are widely available. The only element requiring preparation time is the purple body paint — allow 30–45 minutes for application. Everything else is straightforward costume assembly. Total cost typically runs $60–$120 for a full store-bought build.

Ariel is the most immediately recognisable pairing — the red-haired mermaid princess against the lavender Sea Witch generates instant recognition. King Triton, Prince Eric, Sebastian, and Flounder complete the Little Mermaid world. For a broader Disney villain group, Maleficent, Cruella de Vil, and the Evil Queen all pair effectively with Ursula’s theatrical aesthetic.

Ursula wears a gold nautilus shell necklace — a snail shell pendant that plays a central role in The Little Mermaid’s plot when she uses it to trap Ariel’s voice. For the costume, a snail shell pendant necklace is the character-accurate accessory and one of the details that most clearly communicates Ursula to anyone familiar with the film.

Ursula is the main antagonist of Disney’s 1989 animated film The Little Mermaid, one of the defining films of the Disney Renaissance. She is a cecaelia — half human, half octopus — who was banished from King Triton’s palace and now strikes deals with merfolk from her lair in the deep. Voiced by Pat Carroll, Ursula is widely regarded as one of Disney’s greatest and most beloved villains.
