I think the most important qualities that all the 迪士尼 Princesses share are their moral values and 爱情 for others. It's also important to never give up, to treat others as 你 would like to be treated, and to be passionate. Apart from being royalty, all the princesses have their eye set on some kind of goal (ex: going to a ball 或者 finding adventure), a hobby they're passionate about (ex: painting 或者 collecting artifacts), and a really strong 爱情 for someone in their life (ex: significant other 或者 a family member). An animal sidekick is a bonus 哈哈 :)
Aurora, Tiana and Rapunzel are the only ones who wear crowns. 你 could say that 茉莉, 茉莉花 is wearing a freestyle untraditional tiara simply because she has a royal jewel in the middle of her headband. But that’s it. The others do not wear crowns. Sorry this was @MsPotato
