The Chartered Trading Standards Institute (CTSI) recently reported that 91% of the children’s Halloween costumes assessed in a test-purchase investigation failed to meet legal UK requirements.
Halloween is all about dressing up, embracing the spooky season, and enjoying a few frightful festivities. But while witches, vampires and skeletons might be part of the fun, an unsafe costume can turn an evening of trick-or-treating into a real-life horror story.
The frightening truth about Halloween costume safety
Halloween costumes might look harmless hanging on a shop rail or displayed in an online listing, but appearances can be deceiving.
In October 2026, the Chartered Trading Standards Institute (CTSI) reported that 91% of the children’s Halloween costumes assessed in a test-purchase investigation failed to meet UK legal requirements. The investigation focused on costumes sold online by overseas third-party sellers and identified problems including missing safety warnings, inadequate labelling and a lack of information identifying the responsible manufacturer or importer. Although these findings should not be treated as a representative estimate of every Halloween costume on sale, they highlight serious concerns about product safety.
Fire safety is another major concern. Children’s fancy dress costumes are generally regulated as toys rather than ordinary clothing, meaning specific toy-safety requirements apply. However, even a compliant costume can burn if it comes into contact with a naked flame.
The risks are not limited to fire. Poorly fitting outfits and dark coloured clothing can all increase the likelihood of accidents.
The good news is that taking a few sensible precautions before heading out can help reduce these risks.
