You know, I been seeing Marisa in that particular dress for quite the while, yet I never seen it displayed in any of the actual games.

Just what was the origin of how Marisa got to wear that dress.

It's her outfit in Curiosities of Lotus Asia. Since it's official, that pretty much means this dress is an official outfit for her.

I kinda wish they'd used that design for her Figma. It's really nice.
