Cecilia from So Tei Tei shares a tutorial on her blog for making a mermaid costume. The tricky thing with mermaid costumes is how to create the fins – after all, little girls have legs and feet! In her approach, the fins come courtesy of a perfectly shaped ruffle at the bottom of the skirt. The skirt and ruffle extend all the way to the floor, making the telltale human legs and feet disappear. Get the tute.
