Kick-off a green Halloween season at Portland Children’s Museum at our annual children’s costume swap! Museum guests and members are invited to donate their gently used children’s Halloween costumes, costume pieces and accessories, and exchange them for costumes donated by others. This is a great way to save money, clean out your closet, and connect with other families in the community. Costumes for infants to age 12 are welcome and should be in good to excellent condition. Please no significant stains, rips, holes etc. unless they are supposed to be there! You may also donate costumes without exchanging. Any costumes remaining after the program will be donated to Goodwill. Free with Museum admission or membership. Adults must be accompanied by a child per our admission policy.
