Just some variants of Primarina but based on musical fashions! From top-left to bottom-right: 80s Glam Rock, 90s Rave, Regular Primarina (center), Hair Metal, 50s Jazz.

I should doodle some more some time cause they're fun! My fashion knowledge is not super great though.

I printed these as vinyl stickers as well! You can purchase them in my store if you're interested.
