My dream outfit/overall portrayal for Daisy is simply her in her sports outfit- the official design. It's my most favorite outfit of hers, and looks sporty, yet elegant and stylish because of the matching colors, the jewelry, and her white collar. It ticks me off a lot when I see a drawing of Daisy without a crown or when the white collar is missing from the sports outfit. Ugh! lol
However, if I had to change Daisy's overall appearance, I'd make her have darker skin, or completely change her to black. Even if she was black/had darker skin though, I would like to keep her hair style, since I think it looks really pretty. And I would keep her eye color as blue (or make it green) to make her look like more of an exotic African girl. I mean, Daisy being white is cool, but I just think it would be nice if the Mario series had more diversity, and to me, Daisy would've been perfect to make dark or black mostly because she had that skin color in the old Mario 64 games and because she comes from a place (Sarasaland) similar to Egypt.
I'd also make her thicker and a lot less skinny.
For example, I really love this cartoon artwork of Peach and Daisy because you can see a big contrast between them.
