The size isn't specified, but it has a relaxed silhouette and is roughly equivalent to M to 2XL (^^) It's stretchy and comfortable♪ The color is black. Total length is about 128 cm. Width is about 50 cm. On me, I'm 158 cm tall, and the length covers my ankles♪ It also has side pockets, which are convenient♪ If you have any questions or concerns, feel free to comment (o^^o) #Overalls #Salopette #Jumpsuit
