Is it safe for kids to wear costumes from Halloween stores?
For short use yes. Long daily wear no. Costumes carry flame retardants, PVC, and lead paints.
What's actually in it
Halloween costumes are polyester with PVC accents, metallic paint, and chemical finishes. Costumes are often treated with flame retardants to pass kids' clothing safety rules. Cheap costumes from dollar stores have historically tested positive for lead in painted accessories.
What the research says
A 2025 study in Sci Total Environ showed flame retardants transfer to skin during wear. A 2025 study documented lead leaching from painted items.
For a 2-hour Halloween use, risk is limited. For daily dress-up play, costumes should be washed first and worn over a cotton shirt. Skip painted accessories for young kids.
