there is a size chart on the page the pants are on, right by the size option button...
I have a 1X and it says it's a 16W. I actually wear a 20/22W and these fit but the waist is tight. When I bought my size the legs fit nicely but the waist was way too big and it stretched out a bit after time. I figure these will loosen up too and be perfert. So far so good.
1x 2x and 3x. Are the plus sizes. I belive the 2x is 20/22
1X fits 16-18 and 2X is 20-22...
I got the 2x and it says on the tag that it is an 18-20.
These pants run true to size but are stretchy with no buttons, zippers, belt loops or drawstrings so if you/spouse wants something that is snug go down a size. If you want something comfortable fitted use your regular size. If you want something big or to grow in (maternity style) go up a size. Since there's nothing to adjust the size of the pant with you really have to order based on how you want the fit to be. Walmarts got the best return/exchange policy though so no worries!
FYI: Womens sizes at walmart tend to to run 1x is 14-16, 2x is 18-20, 3x is 22-24, 4x is 26-28, 5x is 30-32.
**For women if you are on the higher end of a size like you wear a snug size 20 or lose 22 then in these pants you want to to buy the 20 AKA: 2x.
I would say these pants fit like any pant in this size; they do not run big or small but do tend to run long. I would say a size 2X fits 18-20. I generally wear a Women's 18 and the 2X fits great and are not tight.
I only know about the 2X. It is true to the size chart which you can find on the page where you order the pants. They are not 16-18. I'd guess the size to be 20-22 but check the size chart to be sure.
1x would be 14-16 and 2x would be 18-20
