>>24751136>>24751274>Though it would suck having a dress practically made out of thin flesh.Exactly. Not everyone likes the idea of the dress being attached skin, so a good amount of artists draw it as a removable dress.
It allows artists to draw Gardevoir in other types of clothes like the OP image without having to worry about the dress making it look stupid.
That, and it means that Gardevoir's body is a consistent and pure white when not wearing any clothes.
