I wanted to see Iron Fist suited up , unlike Daredevil his costume comes with being the Iron Fist , it's ceremonial . The colors , the mask , all of it is a part of being the immortal weapon . As much as I love Iron Fist I've never been a big fan of his original costume , it is very dated . However I would have been fine with a lose adaptation of it until he decides to upgrade to a version of Aja's design or even the track suit version ( which I like ). The whole "we couldn't come up with a reason for him to wear it" excuse makes zero sense to me . Like have you read the comics ? There doesn't need to be a long drawn out excuse as to why he wears it , it's a part of his title as Iron Fist , it's the wardrobe of the the immortal weapon , its traditional and ceremonial . If people accept Steve Rogers running around in red white and blue then people will be ok with this as well. You can only ground these characters in so much realism before you start to lose what makes them great . This is a guy trained in a mystical city by immortal Kung Fu masters and fights a dragon to become the immortal weapon that is Iron Fist , your not gonna make that very real and it's ok because that's what the fans love about it , it's an escape from reality
