I'd still rather see Lorna wearing her iconic costume or some variant of it (ideally a modernized take, e.g. Kris Anka's concept). But my feelings regarding costumes are heavily outweighed by the many plusses of Lorna on this book to date, and this particular costume fits well as a time capsule for the current setting. I could see it being utilized in visual callbacks and setting reminders for this period in the future, e.g. if someone were to delve into her mind then Lorna wearing this costume would be easy shorthand for "Oh, it happened on Krakoa."
