Shein Curve jeans sz 3X white EUC 18W ? 20W ?

Here's an almost new pair of jeans for you. Fabric is cotton/elastane. Flat front, two patch pockets in back. Closes in front with button & zipper. PLEASE READ MEASUREMENTS. Waist stretches from 18.5" to 21" across. Rise is 13". Inseam is 28.5". Tag is marked a 3X, but I believe the measurements are more in line with an 18W or 20W.
