Womens Black & White plaid dress coat

Womans size large coat looks beautiful dressy or casual with jeans. Lovingly worn but no stains or rips in pockets or lining. Accent bands and buttons at cuffs. Accent buttons at lapels the back and at the strap of the kick pleat lower back. This is a dry clean only piece. 1 of the front buttons 2nd from bottom is getting loose and will need a couple of quick stitches with a needle. Falls to about the knees ( I'm 5'4") At the very top where lapel lays flat at the neck there ss a button hole on 1 side & what appears to be a missing button but when I purchased new there was not a button.
