The costume of a Magical Girl, due to its strong association with the wearer's true self, will inevitably reflect the preferences of the transformer to some extent when it forms. For most Magical Girls, the magical attire they transform into represents an image they love or aspire to, so it is undoubtedly something that satisfies them.
Based on this fact, the formation of Magical Clothing extends more operational space. If a Magical Girl has a well-defined idea of her Magical Clothing, whether it is a carefully prepared design sketch or a ready-made garment she has seen before, as long as the thought in her mind about that design is strong enough, it will manifest in her transformed appearance.
So strictly speaking, if a Magical Girl's transformed image closely resembles a certain virtual character, it's not impossible.
