Batman Day is Sept 13th, 2023. The Dark Knight and Gothams supervillians are invited to Suit Up For Jack to help sick kids in their area. This challenge is open to cosplayers in any country around the world. Batman Cosplayers can recognize their special day with a #SuitUpForJack. We are calling Gothams heros and supervillians. If you are a Batman, Joker, Catwoman, Harley Quinn, Red Hood or any sort of a Gotham cosplayer, this is the perfect day to #SuitUpForJack in your city. Its simple, schedule an appointment at your local blood clinic on Batman day and then show up to donate blood in cosplay and watch the fun begin. Don't forget to share your photos on social media with the hashtag #suitupforjack. Let us know in advance and will even create a custom sign for you to hold in donation phtos. Contact us with any questions.
