Grey small plaid Gloria Vanderbilt Amanda slacks, size 20W

This is a pair of black and grey small plaid slacks, Gloria Vanderbilt Amanda style. I’m 5”6 and these come just above my ankles. They were really cute with booties (see grey booties in closet!) Pants have a slimming effect and are very soft. No pilling between legs. Only wore a few times. Missing button on pants but can’t see to sew one one. It’s somewhere so if I find it I will send it. Otherwise, a small black button would work. Smoke free home.
