Short answer: Buy Halloween costumes from a trusted retailer, check sizing and safety labels, keep costumes away from candles and other flames, and make sure masks do not restrict vision or breathing. Add visibility for outdoor trips and test the full outfit before the event. Children should be supervised, especially around roads, batteries and powered decorations.
The Office for Product Safety and Standards has warned about unsafe children’s costumes sold online. A familiar character or low price is not a substitute for traceable product information and a safe fit.
This guide draws on authoritative guidance and the live Meeru Finds catalogue checked on 23 August 2026.
