There's nothing there of value beyond, MAYBE, the pants lol...but you can get (much nicer) pants for $15-30 and save yourself $80. Not sure the belt is included but that's a felony on every level. It does include the mask and gloves etc and those are non-starters. Too many pleats on the sleeves and the material is likely terrible. You can't even 'fix' any of this stuff so it's a waste of money all around.
Much more interesting to me is your comment about the 'make you a costume for a good chunk of change'. Be sure to vet any costume maker and keep on eye on that KoR Facebook group. Remember to ensure that whatever is made for you is tailored for you well so that you can be approved.
