The dress code is post-apocalyptic. Of course!
We will not refuse entering in jeans and T-shirt but you will feel very uncomfortable; for sure!
We recommend you to take the basics if you do not know how to dress, use something dirty, broken or recycling waste products, body protection, gas masks or something in the style of Mad Max or in the sense of S.T.A.L.K.E.R., Fallout, zombies or Star Wars. Dirty your face and enjoy the apocalypse.
