Ariel is one of the most iconic Disney princesses, and wearing an Ariel costume is something many Disney cosplayers like to try at least once. This Disney princess stands out from many classic Disney princesses because of her personality. Ariel is a headstrong and independent princess who takes her life into her own hands. Ariel has always wanted to see what it would be like to live on land. Her father, King Triton, explicitly forbids her from going above the water’s surface.
