H&M Pleated skirt

First picture from H&M site, other pictures from my own product. The skirt has been stored in a closet and therefore wrinkled, which makes it difficult to get an illustrative picture of the fit. Has been worn a couple of times and became too small for me. Skirt measurement at longest approx. 87 cm and waist width approx. 33 cm. The skirt has a zipper and a small hook, material does not stretch.
