Mary Wilson it appears purchased all the gowns available over the years - as she needed them for The post Diana Supremes - I would believe that Diana is a great business woman and did recieve payment for the gowns she left behind - I do not believe she would have donated over one hundred thousand dollars of designer gowns that she wore. And it would have been cheaper for all concerned to buy them and alter them for the next girl _ I believe as one writier wrote - Mary wore Diana;s gowns and Mary's slightly larger gowns got altered to fit Jean Terrell.
