>>47039805Gardevoir's dress is pretty clearly a physical part of it's body and can't be removed. This is the same shit as Sawk and Throh and was even the reason none of them got into the Detective Pikachu movie (they were all originally supposed to be in it until they were told that the "clothes" were actual parts of the body).
Hell, Mr. Mime barely scraped by the cut as it was and was almost disallowed for similar reasons.
