A Harry Potter family costume is an easy way to go all in on Halloween without matching in the usual sense, robes for the parents, a smaller set for the toddler, and even a wizard cape for the dog. Add the glasses, tie, and wand and the whole look comes together fast. Here's everything in it.

Common questions

Do the robes come in different house colors?
Most listings offer a choice of house, so check the options on each product page before ordering.
Is the dog cape easy to put on and keep on?
Look for a simple hook-and-loop or tie closure at the neck so it's quick to fasten and comfortable for a dog to wear for a few hours.
Can the glasses and tattoos be used without the full robe?
Yes, they work well on their own for a low-effort version of the costume if you don't want the full robe set.

That's the full Harry Potter family lineup, robes, wand, glasses, and a matching cape for the dog. It's a costume that stands out from the usual animal-onesie route while still working for the whole family.
