- "My daughter loves playing dress-up as her favorite Disney Princesses."
- "The official lineup of Disney Princesses includes Cinderella, Snow White, Aurora, Ariel, Belle, Jasmine, Pocahontas, Mulan, Tiana, Rapunzel, Merida, and Moana."
In general, when "Disney princess" is used in a more generic sense (e.g., "She dresses like a Disney princess"), it should not be capitalized.
