Kids' Costumes

Sized by height rather than age, made to survive a full evening of running between doorsteps, and just spooky enough.

Children's costumes are sized in centimetres because children of the same age vary enormously. Stand your child against a wall, measure to the top of their head, and choose the nearest size up — they will almost certainly be wearing a jumper underneath on a cold October evening. Everything here meets the toy safety standards required for sale in the UK.

Have a look at girls' costumes, boys' costumes, toddler costumes, classic Halloween and kids' tights.

Order before 3pm Monday to Friday and it leaves us the same day. UK delivery is free over £30 and everything comes with 14 days to send it back.

Frequently Asked Questions

How do children's sizes work?
By height in centimetres, not by age. A size 128 fits a child up to 128cm tall, roughly seven to eight years old, but the measurement is what matters. Measure rather than guess, and round up rather than down.

Are these costumes fire-safe?
They are made to the toy safety standards required for sale in the UK and carry the appropriate labelling. No costume is fireproof, though. Keep children well away from candles and pumpkin lights, and use LED tealights rather than real flames.

Will it be too scary for a young child?
The classic Halloween range — witches, pumpkins, skeletons and friendly vampires — suits primary school parties. Anything filed under scary costumes sits at the frightening end and we would not recommend it for younger children or a school event.
