I'm 5'4 145lbs 8 weeks postpartum. Usually . A medium but have to get small in most motherhood maternity because for me it runs big. Had to get a large in these and it may shape when first going on but constantly rolls down. Sitting down was the worst. Bunched underneath dress and made me look like I had backfat. Not flattering under clothes. Had high hopes. It does flatten stomach but not worth the rolling of fabric.
