I present to you my favorite Barbie transformations based on how much the dress and/or the moment made me gasp. In case you want to judge other transformations for yourself, here's a whole playlist of only Barbie transformations from her movies.
Barbie as Rapunzel: she said SHIMMER. she said Versace but make it medieval. If Donatella could see this, she would give her stamp of approval. Donatella VERSACE 💜. Also, THE HAIR.
Barbie in the Nutcracker: It's pink and glittery and it has sparkles. What else could you expect from a Barbie transformation????
Barbie of Swan Lake: the transformation itself didn't make me gasp but the dress is beautiful and I love the motif of feathers that goes throughout. It could be on the nose for some but I love it. I also have a special place in my heart for that sequence knowing that they utilized real ballerinas to get the animation right, which made me respect it even more. I used to obsessively watch this movie as a kid along with Rapunzel and the Magic of Pegasus.
Barbie and the Magic of Pegasus: ruining a man's life by yassifying yourself à la Glinda from Wicked? Yasssss.
Barbie in The 12 Dancing Princesses : again, love the dancing sequence and the details displayed in the dresses. They look subtle, yet intricate, especially around the neck area. I love it.
