Natori Ultra Max Net Tights

Black Natori open fishnet tights in a size large. Brand new, have not been worn, although they were taken out of the original packaging (which I no longer have) in order to try them on for size. Despite following the size guide on the Natori site, they are unfortunately a bit big for me around the waist. I am typically a size 25 in jeans. The waistband of the tights measures 12.5" across while lying flat. The tights are 40.5" long from waistband to toe while lying flat. They are stretchy however. 92% nylon, 8% spandex. Natori recommendeds that you hand wash and air dry them. You can see the item and the size guide on the Natori site here: https://www.natori.com/ultra-maxi-net-tights/
