eheheh I'm happy you like my cosplay! I know the most known version has the black inverse triangle around neck and Phoenix symbol, but I've seen many arts and with no triangle like this [link] and others! Anyway XD actually I didn't sew my suit cause they gifted me, but I love all the versions!
Yeah, lately even official art has deviated (XD) from the original design. It looks good, I just love the way it was shown in the old comics/cartoon. Its a personal preference though. As long as Jean Grey is still relevant for people, its all good
