POPSUGAR DEMIN front buttons mini skirt retro styl

Super cute brand new with tags mini denim skirt in a dark blue. I bought this on poshmark only to realize that the size 10 was nowhere near fitting me it doesn't have a lot of stretch so I'm re-buying it in a size 14 hoping that that fits...the skirt has these measurements laying flat 15 inches across 18in of length 21 in at hips.
