Blackthorn is still the lower half of a dress and a practically nonexistent bra-ish thing.
That "non-existent bra thing", I don't know what you're looking at, but it's actually a shirt that goes around her shoulders. It's nothing like her default skin. Also, ALL of her skins have her in a dress. What exactly do you want from her? Are you going to complain about Kayle next because "every skin is still her with wings and armor"? --- "Veil of time descend. Atop the ash tree wend. Light of the stars portend.
