Very cute T-shirt, it is compatible with the description. The shirt is of a very soft and pleasant to the touch material, inside there is a label but it is written in Chinese I think, so it is not clear what material it is made of. Wearing it and removing it, I felt the electrostatic discharges typical of synthetic materials, so I think it is synthetic, perhaps viscous given its softness. The shirt has a sharp cut neck, ie the neck is not finished with the seam. The color is a bit more off than the product photo the size is suitable, I usually wear a S. The shirt does not seem to be transparent. It was shipped fast, everything perfect thank you!
