Where to buy Halloween costumes online in 2026

Eighty-three percent of the costume shelf is one resale site. Here is who sells the rest, and what for.

Last verified 17 September 2026 against 2,014 US costume listings from 14 searches, with stock read from each listing’s own feed row

What the costume shelf looks like

We ran 14 costume searches on 17 September 2026 — adult, men’s, women’s, plus size, kids, toddler, witch, vampire, pirate, superhero, couples, cosplay, dog and the unqualified halloween costume — and kept 2,014 distinct US listings. They came from 13 sellers, and one of them is not a shop:

Prices checked 17 September 2026 Poshmark holds 1,670 of the 2,014 listings (83.0%). Every other seller put together holds 343. If you want a costume from a shop — new, in a size you choose, with more than one of it — the real choice is the shops below Poshmark, and in practice the top four.

A note on the last column, because it matters for shopping and for linking. Poshmark marks every listing in stock, so its 100% tells you nothing. Abracadabra NYC writes the field three different ways in one feed — in_stock, out_of_stock and out of stock — so a checker that looks only for the words with spaces reads its whole range as unavailable. We caught that on this run and read all three.

The shops, one by one

• Worth a look for a pet, not for a person.
• This listing: a Care Bears Grumpy Bear dog costume at $12.49.

Poshmark: 83% of the shelf, and why it is a different kind of shop

Poshmark appears in all 14 searches with 1,670 listings and a median of $25.00. It is where the volume is, and it is the cheapest route for most kinds of costume — see the price comparison on what a Halloween costume costs. Three things make it a different purchase from the shops above:

• One garment, one size. Each listing is a single item from an individual seller. If it is not your size, there is no other one.
• Titles are thin. Of 52 distinct listings in the unqualified halloween costume search, 36 were titled with only those two words. You browse by photo.
• No stock signal. Every listing reads in stock until it is gone.

We do not show seller photographs on this page. Marketplace photos are individuals’ own pictures, often of people wearing the costume, and they are not ours to republish.

Which shop for which costume

What this cannot show

• Costume shops outside this affiliate catalogue. Big-box chains and seasonal pop-up stores that do not publish a feed through this network are invisible here. This is a map of where you can buy through a link we can check, not every costume shop in the US.
• Quality, sizing or delivery. We have not bought or handled any costume. Every figure comes from the listing itself.
• Stock next month. Read on 17 September 2026. The in-stock column will fall as October goes on.
• Children’s ranges in full. We searched kids and toddler costumes and they are in the counts, but this page does not picture them.

Method: 14 searches, 3 pages of up to 100 US rows each, CJ shoppingProducts, 17 September 2026; each row’s own country field must read US; deduplicated on retailer, title and price within a search and on title and price across searches; books, wall art and CJDemo removed. A listing counts as in stock if its availability field reads in stock or in_stock.
