This is a set consisting of a single-button, black, slim-fit jacket and skirt. It is 100% wool. Sizes: Jacket: 9 (Japanese size) Shoulder width: 38cm Length: 58cm Skirt: 11 (Japanese size) Waist: 34cm Hips: 46cm Skirt length: 56cm Product purchased at Aoyama. - Color: Black - Design: Single-button jacket - Pockets: Front pockets - Material: 100% wool - Style: Slim fit Thank you for viewing. Regarding the skirt lining (see the last photo), the seams have started to come undone slightly, likely due to frequent sitting and standing. I have repaired it. If the wearer is a size M, there should be plenty of room and no problem. However, if the wearer is a size L, the lining seams may come undone again. Please check the last photo! There is no problem with the exterior. Despite being 100% wool, it is wrinkle-resistant, and the design and sewing are excellent. It is still a wearable product. The skirt is included as a service!
