H&M Mama knot detail satin maternity dress

Calf-length Maternity dress in softly draped satin with a sheen. Boat neck at front, decorative knot detail at front for a draped effect, and V-neck at back. Concealed zipper at back with hook-and-eye fastening at top, shaping darts at back, and a high slit at back of hem. Unlined. Model in the picture is 178cm/ 5’10” and is wearing a size S. I found like so many maternity dresses it runs rather big. I’m 5’10” and usually a size M. And at 8 month pregnant it fit me great. Only worn for one occasion. New like condition.
