A cute and easy little mermaid costume that was homemade, including the wig!
To make the wig, get a large doll or stuffed animal about the size of your child's head. Place an old cap or a new one made from material over the head. Cut pieces of the red felt and hot glue to cap to create a red wig.
Cut shiny green material into the shape of a tail or skirt and sew to bottom of shirt to create a "dress."
Sew tulle around top of fin.
Take a piece of tulle and gather one end to create a flipper and sew it to the bottom fin. Repeat.
Cut out two shell bra pieces from the purple felt and hot glue to shirt.
Embellish as desired. Your Little Mermaid is ready!
