These two lovely ladies apparently have the same great taste in fashion. Kathryn recently pointed out on Twitter that Katy also once rocked that red-hot Marchesa gown that the Southern Charm mom wore to this season's reunion.
Katy stole the show in the Marchesa gown at amfAR's 23rd Cinema Against AIDS Gala on May 19, 2016.
Kathryn looked sexy and sophisticated in the Marchesa gown at this season's Southern Charm sit-down.
Kathryn even cast her vote for who wore it best, giving it to the "Swish Swish" singer. But we think both ladies looked equally stunning.
