I'm a US size 16p in stretch 18p non-stretch on this site, I purchased a 18p in these because of the description and they fit comfortably loose! The jeans look like the photograph on the website, the details are as photographed also, they have some stretch in them so you probably could just get your regular size. I'm only 5'3 so they run long on my frame in flats but works well if I have on a 4 inch heel. The style is flattering on plus size frame!
