It's a shame that there have barely been any films with outfit changes to add some new life to a thread like this since.

Really just
Frozen II. I do like Raya's outfit and Verona's dress. I like Namaari's overall design, but the look itself isn't really a standout. I like that they used for Mirabel's skirt, but that's about it. It's not really just the female characters, even the male characters had more looks back when.
1. Tiana (bayou wedding gown)
2. Cinderella (silver ball gown)
3. Anna (green dress)
4. Belle (red Christmas dress)

6. Tiana (white dress with fur)
7. Aurora (blue dress)
8. Elsa (
OFC winter dress)
9. Elsa (
Frozen II white dress)
10. Cinderella (wedding dress)
11. Ariel (wedding dress)
12. Mulan (matchmaker dress)
13. Anna (
Frozen II green queen dress)
14. Jasmine (purple dress/not ending)
15. Cinderella (pink dress)
16. Jasmine (
King of Thieves wedding dress)
17. Anna (
Frozen II white formal dress)
18. Ariel (sea foam dress)
19. Belle (gold ball gown)
20. Jasmine (ending purple with the see-through veil)
21. Moana (normal outfit)
22. Ariel (pink dress)
23. Namaari
24. Mulan (ending clothes)
25. Anna (traveling clothes)
26. Tiana (green dress at the very end)
27. Moana (pink chief outfit)
28. Ariel (blue dress)
29. Raya (with hat and red coat included)
30. Belle (winter dress and coat with white fur)
31. Belle (blue dress--never really thought about it before, but it's actually similar to Alice's dress)
32. Anna (black dress)
33. Megara (pretty basic, but I do like it)
34. Pocahontas (the white dress from the sequel)
35. Belle (green dress)
I didn't think I should include Ariel's mermaid look, to be fair; I mean, her outfit is a pair of seashells and that's it.

The colors of her hair, shells, and tail do work very well together though. I mentioned it that post from years ago, but I still do love Odette's main dress (including the false Odette's black and red dress). Also Thumbelina's grey dress (once her hair is back to normal) is nice and especially the wedding dress is gorgeous, imo (lovelovelove the way the hair is done). I love the blue dress Vanessa wears while on the topic of villains--better without the cape. Maleficent, Cruella, and Tremaine all have great outfits. Verona in
Raya is very pretty, too. Yzma's travel dress with the cap is good, but my favorite of hers is the pink empress dress she wears after Kuzko's funeral. It's a shame it's blink-and-you'll-miss-it. Like with Ariel, love Ursula's design, but it's hard for me to think of her outfit as a dress so much as her body.
We should make a thread like this for the male characters, too, actually. Aladdin's Prince Ali design, his purple "wedding" outfit, Kristoff's green outfit in
Frozen II, Tarzan in his father's suit, The Prince from
Snow White, Eric (black clothes), Human Beast in his ballroom clothes at the end, Naveen's bayou wedding and church wedding outfits as well as the prince costume, etc. They have a lot of great ones, too. As far as male villains, Shan-Yu with the fur coat was always great.
