Every time a pic of her is disseminated the fashion brand gets free advertising. I thought the wedding dress was ghastly but it got Givenchy 2.5 mil in free advertising the day of the wedding and now it is on display at Windsor. So worth it for them. Plus remember the fashion houses make their profit from smaller items like scarves, handbags, purses keychains even. So a celeb conscious teen can’t afford the dress but can afford (barely) that purse or scarf.
