User blog:Dorayaki/Theme for Part 3 premium dresses?

We know Part 1 and 2 respectively gives a theme for premium dresses, Part 1 was for main heroines, and Part 2 was for two goddesses. We can forsee that Part 3 will also have theme to feature, and the theme will also determine which idols from respective theme can luckily obtain new premium dresses.

I personally don't think Parade series would last long, so sadly and unlikely, not all past idols can manage to obtain new premium dresses. Given not all possibilities would be fulfilled, I'm curious what themes would BANDAI choose to add before Parade series make an end.

On the other hand Raki's lucky dress design mode might also be a hint. We've seen her design a cute premium dress and a sexy one, so probably Part 3 would go with a cool or pop theme so that Raki can do a different type then.

My prediction includes:

(1) Gothic theme: Lily, Sakuya, Kaguya / Raki inspired by Lily (2) Stylish theme: Aoi, Rin, Rei / Raki inspired by Rin (3) Circus theme: Kaede, Ako, Mirai / Raki inspired by Kaede (4) Aikatsu Tour: Miyabi, Kokone, Nina / Raki inspired by Kokone (5) Fanfavorites: Yurika, Koharu, Coco / Raki inspired by Coco (not quite likely since the anime was created before the official ballot) (6) Any other theme idea you think also quite possible?

I think (1) is the most likely one, followed by (4), (2) and (3).
