As runners await the latest runDisney registration updates and new on-sale calendars, let’s think wardrobe. Whether you are princess-leaning or stormtrooper trending, half the fun of a Disney contest is becoming an active piece of their storytelling. To celebrate the 30th anniversary of a Disney beloved under the sea classic, here’s our recommendation for what to wear to runDisney; take the plunge with our The Little Mermaid costume.
