Catherine Cottage pannier, length is 46 cm. Made of one layer of nylon fabric and two layers of stiff, structured lace, the volume can be adjusted. Purchased several years ago and worn only once for a short time. The waist is adjustable with elastic. My daughter wore it when she was 5 years old, but it should be quite adjustable. There are no noticeable scratches or stains, but I will sell it to someone who understands that it is used.
