Three stained Cintas men's pants with stretching waistbands

Three pairs of navy blue Cintas brand men's pants with stretching waistbands. Label says size 28, which must be a length measurement, because they have the same waist size as the size 44 pants. They are 65 percent polyester, 35 percent cotton, and have 2 side pockets, and 2 back pockets- 1 that buttons closed and 1 that doesn't. I've included photos of each one. All have several small stains that a dry cleaner might get out, but I couldn't. One is missing a waist button, but you could sew the back pocket button there instead.
