Product Description

A Magical Transformation

Ariel spent a lot of time looking at the land in a world apart of her own. Of course, knowing that Ursula had the ability to let Ariel take a long walkabout is probably part of what made Triton nervous. Of course, we humans on the surface spend just as much time looking into the waves, wondering what it would be like to be part of their world, too. While we haven't quite figured out how to do that in full, there are plenty of options to feel the magic.

Of course, we can't just dial up Ursula on our shell-phones and sign a digital contract for a fin of our own. Unless, of course, we channel some of the magic of the sea witch, herself! With a little bit of help from one of our favorite costumes, you'll be able to sing out a few bars of your favorite tune and join the world of The Little Mermaid.

Fun Details

Transform into one of the most notorious (and beloved) Disney villains out there with this officially licensed Little Mermaid Ursula Prestige Costume! Not only does this multi-part costume let you take on Ursula's look, you can transform the silhouette to your liking on the spot!

Start with the long-sleeved mesh shirt to give yourself and undersea under layer. Next, the satin bodice is trimmed with shiny sequins that turns into layers of glittering tulle over a black skirt. The conch shell necklace is a critical component for this magical ensemble. That may be perfect for your night under the waves, but you can bring the whole look to life when you inflate the overskirt to complete your transformation with a set of tentacles at your waist!

Questions & Answers 

Q: What size is the model wearing (1 Answer)
Asked by Anonymous | 17 October 2025
Monster Responds...
The size the model is wearing isn't something we have noted, but our size chart is the most reliable guide for finding your fit. For reference, the 2X has a 50" dress chest and 47" waist, and sizes go up to a 5X with a 56" chest and 54" waist, so comparing your measurements to those numbers is the surest way to choose.

Q: How wide is the waist of inflatable dress. Sizing guide does not specify this (1 Answer)
Asked by Jellie | 16 October 2025
Monster Responds...
The dress waist measurement is what determines where the inflatable overskirt attaches, since it fastens at the waist with a hook and loop closure. The dress waist measures 47" at 2X, 50" at 3X, 52" at 4X, and 54" at 5X. Comparing your own waist measurement to those numbers is the surest way to choose the right size.

Q: On average, How long will a set of batteries keep the tentacles inflated for ? (1 Answer)
Asked by Nick  | 6 October 2025
Monster Responds...
That's a great question, but battery runtime isn't something we have a specific figure for with this costume. What we can tell you is that the inflatable overskirt runs on 4 AA batteries housed in a concealed pocket next to the fan, so using fresh, high-quality alkaline batteries will give you the best performance on the big night.

Our size chart is the most reliable guide for choosing the right fit, but the specific size the model is wearing isn't something we have noted. Comparing your measurements to the chart is the surest way to find your size, with dress chest measurements ranging from 50 inches at 2X up to 56 inches at 5X.

Q: Is the purple shirt separate or is it sewn into the bodice? (1 Answer)
Asked by Hunty | 29 August 2025
Monster Responds...
The shirt is a separate piece. It's a long-sleeved pullover made of purple mesh, designed to give the look of Ursula's purple skin beneath the strapless dress. The two pieces are worn together but are not attached to each other.

Q: Hi. I was wondering if the wig is included. Thank you (1 Answer)
Asked by Jackie | 20 July 2025
Monster Responds...
The wig is not included. This costume ships with the shirt, dress, necklace, inflatable overskirt with attached fan and battery pack, and instructions. You would just need to add a wig separately to complete the look!

Q: Hi … is the purple sleeved suit attached to the main bodice or is it a seperate piece under the black bodice? Ie .. could I wear the black bodice without the purple sleeved suit? (1 Answer)
Asked by B | 10 October 2024
Monster Responds...
The purple mesh shirt and the strapless dress are two separate pieces. The shirt is a long-sleeved pullover you wear underneath, and the dress goes on over it. You could absolutely wear the dress on its own without the shirt, and the dress has a concealed back zipper plus a boned, underwire-supported bodice to keep everything in place.

Q: Hi, do you have the size and weight of the package dimensions please? I'm travelling with this. Thanks (1 Answer)
Asked by Sarah | 2 October 2023
Monster Responds...
Package dimensions aren't something we have on hand, but the costume itself is a soft garment set, so it folds down quite compactly for travel. The heaviest size in this range comes in at just under 48 ounces, so the whole thing is light enough to tuck into a bag without much trouble.

Q: Is the costume noisy when the blow up fan us running? (1 Answer)
Asked by Sara | 9 September 2023
Monster Responds...
That's something our copy doesn't give a decibel rating for, but inflatable costume fans are generally a small, low-powered motor, similar in sound to a quiet desk fan. The fan on this costume is installed at the back of the left hip, so it sits away from your face and is partially muffled by the inflated overskirt surrounding it.

Q: How long will the tentacles stay inflated or do I have to have the fan turned on permanently (1 Answer)
Asked by Jeanette | 2 August 2023
Monster Responds...
Good question. The tentacles may stay inflated for a short period with the fan off; but, for best results, you will want to leave the fan turned on.

Q: Can you sit down in it? (1 Answer)
Asked by Anonymous | 9 October 2022
Monster Responds...
Who needs to sit? I don't expect that sitting with the tentacles inflated would be very comfortable. However, the inflatable overskirt can be easily removed to allow you to have a seat.

Q: Is it possible to order just the inflatable tentacles on their own? (1 Answer)
Asked by Gillian | 5 March 2022
Monster Responds...
The inflatable tentacles are not currently sold separately from this costume.

Q: How wide and long are the individual tentacles? (1 Answer)
Asked by Anonymous | 25 February 2022
Monster Responds...
We decided to keep our evil squid true to nature. The width and length of the individual tentacles is varied.
