Smiling babies and toddlers in Halloween outfits at home

Baby & Infant Halloween Costume Ideas

Dressing a baby or toddler for Halloween works best when the outfit stays soft, warm and quick to change. These picks suit the littlest ones, and the smaller sizes fit toddlers who are still finding their feet.

How we chose: we favour soft, warm outfits, simple shapes that pull on fast, and looks a small child will actually keep on. Each pick links to its product page and shows what it is best for and a rough price band, so you can choose fast.

Frequently asked questions

What is the easiest Halloween costume for a baby?

A soft, one-piece outfit like a little dog or a bee works best. Pick something warm that pulls on fast and comes off just as quickly.

How do I keep a toddler warm in a Halloween costume?

Choose a roomy outfit and layer it over a jumper and leggings. Sets with a tutu or a tabard go over warm clothes without a fuss.

What size should I pick for a very young child?

Sizing runs generous, so size up if you are between ages and want room for a warm layer. A slightly loose fit lasts longer and stays comfy.
