On Tumblr I found this link that analyzes the superhero-attires of the series' Miraculous Holder:

Basically, this page analyzes the personalities of the various Miraculous Holders ONLY and EXCLUSIVELY by their costumes (I do NOT speak about the colors and the animal of the Miraculous, but about the structure of each costume).
I mean, the various historical Ladybugs we saw in the series had only the red color and the black spots in common, but for the rest they had completely different costumes, which surely represent their individual beliefs and dreams about what a real hero is.
I think if Marinette used the Black Cat Miraculous, she would not have the same identical Chat Noir's costume, but a costume that best suits her and her personality.
Something like this

So: can you be able to analize Ladybug's, Chat Noir's, Hawk Moth's, Vixen's, Queen Bee's and Le Paon's personalities ONLY by their costumes?
