Our pick for the best witch costume for kids in 2026 is the Girls Purple Witch Costume: a purple velour dress with a layered skirt and an ombre bodice, and a bat-detailed pointed hat, sized 3-4 years through 12-14 years. Purple is the look parents search for most. Then pick by look: gothic black, rainbow, classic black, or the two-headed scary one.
Purple is not a guess. Between September 18 and October 22, 2026, 58% of the U.S. Google impressions our site earned on kids' and girls' witch-costume searches came from searches that named purple. Witch is also tied for fourth among children's costumes this Halloween, with 1.6 million kids, according to the National Retail Federation. Every pick sits in our kids Halloween costumes range, alongside our best kids Halloween costumes guide.
Which witch look suits your child?
Purple and rainbow suit a child who wants color, gothic and classic black suit one who wants to look older, and the two-headed witch suits a child who wants to scare. Of the U.S. Google impressions our site earned on kids' and girls' witch-costume searches this fall, 58% came from searches naming purple, 10% gothic, 10% black or wicked, 8% rainbow, and 6% scary or horror; the rest named another color or none.

What comes in each kids witch costume pack?
The dress is the one piece every pack shares. Hats, headbands, tights, a wand, a mask, and gloves vary by pack; shoes, brooms, and face paint come with none. Check each product page's pack list, and plan shoes for the walk.
The gothic witch for a girl who wants to look older
The Girls Dark Princess Gothic Witch Costume is a black satin midi dress with glitter mesh overlays and puffed sleeves, with a fabric tiara headband in the pack. No hat, so nothing tall gets knocked off in the parade line. It is 100% polyester and sized by age in S, M, L, and XL; tights and shoes are not in the pack.
The two-headed witch for the child who wants to be scary
The Kids Two Headed Witch Costume packs a black witch dress with an attached purple cardigan, a two-headed witch mask, a black hat, and a pair of gloves. It is the only pick here with a mask, so it is the trick-or-treat witch; the mask comes off for school and at crossings, and the rest still reads as a witch. Sized by age in S, M, L, and XL.
The rainbow witch for the youngest in the line
The Girls Rainbow Star Witch Costume is the one pack here with tights: a layered rainbow star dress, stripey tights, a pointed witch hat with a colorful band, and a rainbow star wand. It is sized by age from 1-2 years to M (7-9 years), with an elastic waistband, so it reaches the younger sisters the purple witch does not.
Two more looks: our Girls Black Wicked Witch of the West Costume for classic black, and the Girls Red Bat Witch Costume in red.
Can my child wear a witch costume to school?
Yes, if the mask and the props stay home and the dress meets the school's dress code. All three school Halloween rules we read, from two districts in California and Utah, ban masks; one bans magic wands by name; none mentions hats or headbands. The two-headed mask and the rainbow star wand stay in the bag on costume day.
The three rules, from recent years:
- Castlemont Elementary in California: costume on over regular clothes, no masks, and costumes off straight after the parade.
- Forest Hill Elementary, also in California: no masks, no weapon-like props, shoes fit for school, and a change of clothes.
- Heritage Elementary in Utah (a costume-day guideline, not a parade): no masks, no toy weapons or wands, no inflatables, costumes kids can get in and out of for the restroom, and the regular dress code on skirt length and necklines.
That restroom rule is the practical one: a dress over leggings and a T-shirt comes off fast, and a hat or tiara headband fits in a backpack. Check the dress's length and neckline against your school's dress code, and read this year's rule; the pages above are from past seasons.
How do you make a witch costume safer for trick-or-treating after dark?
Put reflective tape on the dress and the candy bag, bring a flashlight after dark, and check the hem clears their shoes. All three come from the American Academy of Pediatrics' Halloween costume advice. Our own addition: dark fabric hides a child at night, so the black and purple dresses need the tape most.
A JAMA Pediatrics study of four decades of U.S. crash data found pedestrian fatality risk 43% higher on Halloween, highest around 6 p.m., with the largest increase among children aged 4 to 8. So an adult walks with the younger ones, and the two-headed mask comes off at every curb; Consumer Product Safety Commission guidance says any mask should have holes large enough for full vision.
What should a child wear under a witch costume on a cold night?
Leggings and a long-sleeved top: black under the black and purple dresses, any color under the rainbow one, because its striped tights go over them. The purple witch is a stretchy 100% polyester dress, not a coat, so the warmth comes from underneath, and its product page says to size up between sizes for layering over warmer clothes.
Pick the size with the layers on.
What size witch costume does a 4-, 7-, or 10-year-old need?
A 4-year-old takes 4-6 years (the purple witch also comes in 3-4), a 7-year-old 7-9 years, and a 10-year-old L (10-12 years) in the purple witch and the gothic witch. Every costume goes through over 30 measurement checks. Kids the same age differ in build, so check the size guide first.
- Girls Purple Witch Costume: 3-4, 4-6, 7-9, L (10-12), and XL (12-14) years.
- Girls Dark Princess Gothic Witch Costume: S, M, L, and XL, listed on the page as 4-6, 7-9, L (10-12), and XL (12-14) years.
- Girls Rainbow Star Witch Costume: 1-2 years, 3-4 years, S (4-6 years), and M (7-9 years).
- Kids Two Headed Witch Costume: S, M, L, and XL; the page labels L as 10-12 years and XL as 12-14.
How do you wash a kids witch costume?
Give it a cold hand wash and an air dry; it never goes in the washing machine. Every witch dress we checked for this guide is hand wash only, and the four we feature are 100% polyester. Lay the dress flat to dry, wash the purple witch's dress and hat separately, and store the two-headed witch's mask and hat apart so they keep their shape.
