Wearing a size 18/18W in these dresses! They all run true to size but the satin teal gown is a little tight so I probably would be ok in the 20, don’t hesitate to size up if in between on that one. As far as shapewear goes, I wear a 3X in the satinX! I recommend sizing up one in that particular style!
