Grey gray suit office pencil skirt

Gray business skirt by H&M, with full lining. This is from about 2014, lovely quality. Slit, darts and small pocket at back. Button and zipper closure at center back. Worn once or twice, the skirt is in new, perfect condition. Clearly, I now need size 8 or 10 for comfort. Brand and size tag removed, but I believe this is size 6. Measures: waist - 14" across hips - 18" across length - 21" Bundle with other items from my closet for maximum savings.
