Have you seen the descriptions for some of the Part 2 dolls? I think the outfits sound really cute!
All credit goes to this webpage. I marked this as spoilers just in case, because it does give descriptions of outfits, and you may not want to know about them before seeing the movie.
The first couple of dolls don't give much away, they're presumably going to be these outfits.
WICKED 2 PREMIUM ELPHABA DOLL
The Elphaba Premium doll wears her iconic hat, grimmerie, broomstick and black boots. With green skin and black hair, the Elphaba doll enchants with a look faithful to the movie.
WICKED 2 PREMIUM GLINDA DOLL
The premium doll Glinda Il wears her lilac dress, with a pink wand, high heels and a tiara, looking faithful to the movie with her characteristic hairstyle and blonde hair.
The next two, however, I find interesting! Keep in mind these are what I assume to be placeholder descriptions, but if these are accurate then Elphaba may wear something multicolored and patterned? Glinda in lilac with butterflies sounds really cute.
WICKED 2 SINGING ELPHABA DOLL
Sing with Elphaba! Press the button to hear excerpts of her song,
“For good”. Elphaba wears a multicolored patterned dress inspired by her movie cover. Her long hair and green skin complete the movie-inspired look. The Elphaba doll is a musical gift for fans of the musical, who will want to sing along.
WICKED 2 SINGING GLINDA DOLL
Glinda is ready to sing! Press the button and sing excerpts from her song, “For good”. The character wears a lilac dress with a butterfly print. Her long blonde hair completes the movie look!
Lastly, the "bubble" doll - the outfit description sounds adorable.
WICKED GLINDA BUBBLE DRESS DOLL
Glinda with her fabulous dandelion look from the Wicked movie 2, based on the content when she is gifted her iconic bubble machine to float on OL, dressed in a pink glitter print skirt, matching jacket with soft mint green tulle ruffle and amazing accessories: hair clips, earrings, scepter and spectacles.
