The same survey says families will spend about $1.5 billion on children’s costumes this year, so a few smart picks go a long way.

How to pick the right size for kids Halloween costumes
- Size up if your child is between sizes. Most kids Halloween costumes are cut slim. A slightly bigger size leaves room for a warm layer underneath.
- Check the size chart, not just the age. Use height and chest measurements on the product page. A “medium” from one brand can fit very differently from another.
- Plan for the weather. Leggings and a long-sleeve shirt underneath make a thin costume warm enough for a cold night.
- Do a test run. Have kids wear the costume at home for 20 minutes. If the mask or headpiece bothers them, swap it for face paint.
Halloween safety tips for kids’ costumes
- Look for “flame resistant” on the label of costumes, wigs and accessories.
- Add reflective tape or a glow stick to dark costumes like the ninja, Batman or Grim Reaper.
- Make sure kids can see. Masks that slip over the eyes are a trip hazard. Face paint is safer for younger kids.
- Hem anything too long so capes and robes don’t drag on stairs.
