Anything but fire. I classify Snow as a Cancer, Cinderella as a Taurus, and Aurora as a Libra. This is water, earth, and air. I went with air because air is the most peaceful and least practical, and highly idealistic.

Traits of water.....romantic, elengant, compassionate, grounded, dreamy and hard working. This answer is a dead give away

^I don't find water very grounded, and Aurora and Snow sure aren''t either.

Air adapts well, is flexible, idealistic, and can be stronger than people think.

^yeah, water isn't grounded at all, that's more the earth signs. In fact water is more idealistic than practical.

Water is feminine, sensitive and romantic. I don't associate air with traditional feminity.

Rock solid strength, grounded, generous and giving

@anukriti2409, earth would be my second choice. Extra points for Earth for being the element I am associate myself the least. I have traits of three elements: water( deep thinker, affectionate( I mean all my affections tend to be very strong, I am patriotic)), air( spiritual, imaginative, unconventional) and fire( aggressive). I don't see any earth traits in myself at all. I'm not sure about Cindy and Aurora having earth traits but I definetely see some of them in Snow White. She provides material comfort( which I am completely useless at), she is practically useful, I even asscoiate her with fertile earth( and APPLES!!!). Yeah, I didn't call Snow my oppossite for nothing.
And yeah Classics are generally the least relatable group of DPs to me and the Earth is the element I associate myself the least.
