this was a custom cosplay piece bought on Etsy ($290 new see photos in listing) the seller does not make this anymore so its a one of a kind. easily slip on through the back with velcro and then put your arms through the sleeves. The discoloration in the middle is because that's where the bat emblem was - may require the buyer to customize further to how they see fit, such as an additional coat of black spray paint. Perfect for users with a height of 5'10 or taller.
