A perfect pair.

There are only so many years most kids will tolerate and/or celebrate dressing up in a duo costume with their mom. But while you have them on board with the idea, might as well take advantage of it with these mother/son Halloween costumes.

Imagine the possibilities. You could pull inspiration from your child’s favorite bedtime story, or opt for beloved movie characters. Or, turn to pop culture icons for a funny look — Priscilla Presley and Elvis, anyone? The joy of mom/son Halloween costumes is that you can dress your child as an adult or hilarious fantasy character for optimum laughs. Consider baby carriers. Many parents will be toting their kids in these on Halloween night. So why not use the contraption as part of a duo costume? For instance, safety pin on eight legs and suddenly your cozy baby is a spider and you’re the web. Or wrap them in a spotted blanket and dress them as a Dalmatian while you channel your best Cruella de Vil.

You’ll have twice the fun Halloween night when you join your son in the costume action. So check out these mother/son Halloween costume ideas for the perfect look you can look back on and say “Hey buddy, remember when we dressed up like that?”
