The best Halloween hen party costumes are ones the whole group can wear together, with one look that lets the bride stand out. Build the hen around the Womens Wicked Witch Costume Red, which runs to UK 30, and coordinate the squad in matching horror looks around her. The average UK hen party is 14 guests (The Foxy Hen, 2026), so the job is dressing a whole crew of different sizes, not one person. Here is the countdown from six to one.

The horror hen countdown, from six to one
Six real costumes from our own catalogue, ranked from an easy group starter up to the look we would build the whole hen around. Each is a complete pack with the contents spelled out, so nothing turns up short on the day. If the horror theme is still up for grabs, our best Halloween costumes UK 2026 guide ranks the wider range, and the full Halloween costumes hub carries everything beyond this shortlist.
| Costume | What is in the pack | Size range |
|---|---|---|
| Wicked witch (red) | Dress and pointed hat | S to XXXL (to UK 30) |
| Wicked witch (green) | Dress and pointed hat | S to XXXL (to UK 30) |
| Electric skeleton | Printed stretch catsuit | S to XXL |
| Voodoo priestess | Six pieces: tailcoat, vest, belt, choker, necklace, hat | S to XL |
| Black widow spider | Dress with attached legs, arm covers | S to L (UK 8-18) |
| Skeleton tutu dress | Tutu dress, bone-print gloves, stockings | S to XL (UK 8-22) |
6. Womens Skeleton Tutu Dress Costume
The Womens Skeleton Tutu Dress Costume is the easy starter, and the pick for a hen who wants a skirt rather than a catsuit: a strapless black tutu dress with a white skeleton rib-cage print on the bodice, a layered tulle skirt, and matching bone-print gloves and stockings, all in the pack. It runs from small to X-large (UK 8 to 22) in 100% polyester and goes on in one piece with no assembly. Classic black-and-bone, it sits happily beside any other look in the group, which is what you want from the pick that eases a nervous guest into the theme.
5. Womens Black Widow Spider
The Womens Black Widow Spider is the complete-effect pick: a black-and-purple dress with a spiderweb-glitter bodice and net skirt, extra spider legs built into the dress for a full eight-legged silhouette, and a pair of black arm covers, all included so nothing needs adding. It comes in small to large (UK 8 to 18), and because the legs are sewn into the dress rather than strapped on, it goes on as one piece and stays put through a night of dancing. Wash it cold by hand and air dry it flat.
4. Womens Voodoo Priestess Costume
The Womens Voodoo Priestess Costume is the standout for the guest who wants the most detail: a six-piece set with a voodoo-print tailcoat, a snakeskin-print vest, a red-and-green bones belt, a velvet skull choker, a bones-and-beads necklace and a top hat. Six pieces arriving together is the point; the look lands layered and considered without a single trip to a craft shop. It comes in four sizes, small to XL, and the separate jacket and vest give a more forgiving fit than one fitted piece.
3. Womens Electric Skeleton Costume
The Womens Electric Skeleton Costume is the squad base: a printed skeleton catsuit in high-stretch fabric (87% polyester, 13% elastane) that hugs and moves with you and layers over underwear for comfort. The bright blue electric print stands out in low light, so a row of these reads as one coordinated crew in every photo. It runs up to XX-large, and because the smaller sizes sell through fast in season, order early if your hen skews petite. Hand wash it and air dry it flat to keep the skeleton graphics sharp.
2. Womens Wicked Witch Costume Green
The Womens Wicked Witch Costume Green is the rest of the coven: the same silhouette as the bride's look in a bold green, so the hens coordinate with her without wearing an identical dress. It is a long black-and-green dress with a sweetheart neckline, a corset-style lace-up front and jagged bell sleeves, plus a matching pointed hat, in 100% polyester stretch with a back zip. It runs in six sizes, small to XXX-large (UK 8 to 30), the same wide range as the red, so the whole coven fits from one costume regardless of who is in the group.
1. Womens Wicked Witch Costume Red
The Womens Wicked Witch Costume Red is our pick to build the whole hen around, and the natural look for the bride: a long black-and-red dress with a sweetheart neckline, a red lace-up corset front panel and jagged bell sleeves, plus a matching pointed hat, in stretch fabric that photographs beautifully and moves through a night of hosting and mingling. It runs in six sizes, small to XXX-large (up to UK 30), the widest range in this countdown, so the bride leads in red while the coven coordinate in green. The witch is the most-planned adult Halloween costume year on year (NRF, 2025), which is exactly why a coven of them reads instantly and never dates. Hand wash and air dry, and store the hat separately to hold its shape.
How to coordinate the whole squad
A hen party averages 14 guests (The Foxy Hen, 2026), and the themes that actually work are the ones everyone can join: split a group into some-in and some-out and the photos fall apart. Horror is the easiest theme to coordinate because it holds together across wildly different looks, so a coven of witches, a skeleton and a spider still read as one crew. Pick a lead look for the bride (the wicked witch in red does this job well), then let everyone else choose their own horror character in the same palette of black, green, red and bone.
Sizing is the other half of the job, and it is where a group order usually comes unstuck. Across these six looks the range runs from UK 8 up to UK 30 on the wicked witch, so a mixed-size hen can be sorted from one shortlist rather than three different shops. Order everyone's costume together from the same guide, and you avoid the classic hen-do problem of two guests turning up in looks that do not match because they bought from wherever had their size. If one guest wants out of the horror theme entirely, our best Halloween costumes for women covers the non-scary options, and for the guests who want to lean harder into the fright, best scary Halloween costumes for adults goes deeper on that end.
The wider stag do and hen do costumes range carries the sashes, veils and novelty add-ons that mark out the bride on top of the horror fancy dress itself. A sash over the red witch dress, or a veil pinned to the bride's hat, is the touch that turns six separate costumes into an unmistakable hen party.
Made to last the night, not just the photos
A hen do is a long night of standing, dancing and photos, so comfort earns its keep. Every MorphCostumes design clears more than 30 measurement checks before it ships, and more than 500,000 quality checks run across the catalogue each year, which is the gap between a costume that keeps its shape all night and one that sags by the second bar. The fitted looks here, the skeleton catsuit and the two witch dresses, are cut to move with you, and the multi-piece sets like the voodoo priestess spread the fit across separate, forgiving pieces rather than one unyielding shell.
Fit is the part most groups get wrong. Each costume lists its own measurements on the product page, so match your chest and height to that chart instead of assuming your dress size carries across, and take the larger band if you land between two. On care, the rule holds across all six: hand wash and air dry, never the machine or the tumble dryer. Treated that way, a hen party costume comes back for a Halloween party or a fancy dress night later in the year, so it earns more than one wear.
Frequently asked questions
What should a hen party wear for a Halloween theme?
Pick a lead look for the bride and coordinate the rest of the squad around it in the same palette. A red wicked witch works well for the bride, with the hens in a green witch, skeleton, spider or voodoo priestess look in matching black, green, red and bone. Horror holds together across very different looks, so the group still reads as one crew in the photos even though nobody is wearing the exact same thing.
How do you coordinate a hen party of different sizes?
Order everyone's costume together from one shortlist so the looks actually match. Across our six horror hen picks the sizes run from UK 8 up to UK 30 on the wicked witch, so a mixed-size group can be dressed from the same range rather than from three different shops. Check each product's own size guide before ordering, since the exact fit varies by costume.
What is the best Halloween costume for the bride on a hen do?
The Womens Wicked Witch Costume Red is our pick for the bride: the bold red dress makes her stand out from a coven in green and the rest of the squad in darker looks, and it runs up to UK 30. Add a sash or veil from the stag and hen range to mark her out further. The witch is the most-planned adult Halloween costume year on year, so a red one leads a group without needing explaining.
Are these costumes comfortable enough to wear all night?
Yes, when they are made properly. Every MorphCostumes design clears more than 30 measurement checks, and the fitted pieces like the skeleton catsuit and witch dresses use stretch fabric that moves with you rather than trapping heat. Match your measurements to each product's size chart and take the larger band if you fall between two, so nothing is digging in once the dancing starts.
How do you wash a costume after a hen party?
Hand wash it in cool water and air dry it flat; do not machine wash or tumble dry any of these costumes. Washing dark colours separately stops the prints transferring, and drying flat rather than on a hot radiator keeps the shape. Treated this way, a hen party costume comes back for a Halloween party or a fancy dress night later in the year.
Whatever your hen settles on, every look here carries the Morph Promise: no costume fails, it turns up looking like the photo, and the pack holds everything shown on the page. See the full Halloween costumes range for looks beyond these six, or the best Halloween costumes UK 2026 guide if the horror theme is still open. We make your best times better with costumes.
