I bought this about a year ago for work and wore it during the spring and summer seasons. It has a zipper, but the back also has elastic, so it fits comfortably around the stomach. I'm 162cm tall and weigh 53kg, and the length is just long enough to cover my calves. I think the color in the third photo is the closest to the actual color. It's designed to be opaque, so you don't have to worry about it being see-through (last photo). It spreads out quite a bit when laid on the ground, but when you wear it, it falls straight down while the hem is fluffy, making it cute. I feel like the color and design give it a strong office vibe. *The size is listed as M, but the actual tag says F-M. Thank you for looking.
