These Flintstones costumes use clothes you already have or old ones you don't mind tearing up!
What you need to do: For Pebbles, wear a green shirt and black shorts. For Bamm-Bamm, wear a grey shirt, tie an orange shirt (with scalloped ends) around the waist, and wear shorts. Get black felt, cut out the shapes, and stick them to your clothes using a hot glue gun or tape.
