Got two of this shirt back when it came out in 2017 since it's a very delicate fabric. It's 50% cotton 50 Nylon and the see-through parts had a special bleaching technique so that any clothing you wear under can be seen which allows for great color break ups making it truly a unique piece for any ghost in the shell fan. Because of that delicate nature, it does easily get damaged so when cleaning be extremely careful and put in a bag but I honestly wouldn't recommend and just handwash if you have to. It's hard to show on my camera so this link better shows all the concept art panels across the piece. I've only worn a few times so still in excellent condition (no stains). The other one I own I got custom at a seamster to make shorter which I personally recommend since it's easier to use it with other fits. These aren't easy to come by along with other piece from this collection so don't miss your chance. Sometimes when in Japan i find other pieces from this collection and similar ones from Ground Y if interested. Feel free to ask questions :)
