The short answer
The most popular kids' costume themes this year are dinosaurs, astronauts, witches, superheroes and cuddly animals, with pumpkins and ghosts close behind for toddlers. For educational and character-building costumes, career outfits are the standout: doctors and scientists, firefighters, construction workers, pilots and chefs let children act out a job they admire.
Whatever the theme, comfort and visibility come first. A costume that a child can walk, sit and see in is a costume they will actually keep on.
The most popular themes this year (Ideas 1–5)
Idea 1: dinosaurs. Year after year the most-requested theme for younger children, especially in hooded jumpsuit styles with a tail. They are warm, easy to move in and easy to put on over clothes.

Choose bright colours or add reflective tape to dark costumes so drivers can see children at dusk. Hems should sit above the ankle to avoid trips, and face paint is safer than a mask that blocks side vision — test any makeup on a small patch of skin a day or two before.
Idea 11: glow-stick bracelets. Cheap, fun and genuinely useful: a couple of glow bracelets on each wrist make children visible from a distance, and kids treat them as part of the costume.
