This is a BIG T-shirt, a triple collaboration between MIKIOSAKABE, Ai Madonna, and Dempagumi.inc, sold at WALL for the Cosmo Tour Budokan at the end of 2018. Size is XXL. It's quite large, so it's a unisex size that both men and women can wear loosely. Image 2 is a rough measurement by an amateur, but it should give you a general idea of the size. Color is Mirin Furukawa's (red). It appears to be a puff print, and as you can see in the third image, the red parts have a raised, puffy design. I missed the chance to wear it, and it's been displayed in my room for a long time. I've only tried it on indoors 2 or 3 times, but it's not new, so please refrain from purchasing if you are concerned.
