Trivia
These could be a reference to Princess Peach from the Mario series, Zelda from Legend of Zelda series, or Princess Mi Amore Cadenza from the TV show My Little Pony: Friendship is Magic. The dress matches Princess Mi Amore Cadenza's color scheme perfectly, and the tiara is similar to Zelda's, with a single, dark-colored gem on the front.

The dress is the exact same as Princess Zelda's in Ocarina of Time.
