I felt like this question had never been answered here before.

I own all of them on BluRay with the exception of Tangled and Brave. I used to have Pocahontas on VHS but I'm not sure where it went?

There's only a couple of the older ones I didn't have as a child - although I don't have most of the newer ones - I don't really count them if they're not 2D

I own all of them except Aladdin, The Princess and the Frog, & Brave.
I have The Little Mermaid, Pocahontas, and Mulan on VHS while everything else is on DVD.

I have the Little Mermaid and Aladdin on DVD.

Hmm. Mulan and Mulan II on DVD, The Little Mermaid ( I have 2 copies of it on DVD), Sleeping Beauty on DVD, and then Pocahontas Special Edition on download from somewhere. That's about it. The rest of my DVDs are all non-princess movies, and I tend to collect them more than the princess variety ones.

I have all of them on Blu-Ray and VHS ;)

I have most of the older ones on VHS and have started to get them on DVD, along with the newer ones.

Granted, one of them is in Spanish.

I don't have Sleeping Beauty or The Princess and the Frog, because I don't like either of them enough to be worth the investment. I have all the others on DVD.

Mulan on VHS, Tangled on DVD, and Snow White on VHS (though I think it's gotten lost).

The rest I've watched online.

I downloaded The Little Mermaid, Aladdin, Beauty and the Beast, Frozen, Brave, Cinderella (1950 & 2015) and Sleeping Beauty.

All except Brave. Most are VHS.
