I purchased this from an online shop last year, but I only used the black one and left this one untouched. The waist is fully elastic with an adjustable drawstring. It fit me fine, and I usually wear a size L. Size (measured by hand): Waist: Approximately 35 cm Total length: Approximately 86 cm (lace portion: approximately 12 cm) Color: I believe it's gray. It's new and unused, but please understand that it has been stored by a private individual. I would appreciate it if you would consider purchasing it.
