It seems that in order to have a successful "lifestyle" brand off of the back of celebrity, the key elements have to be: "authenticity". People have to believe that the persona matches the product. So a little vulnerability would be in order. Kate Hudson had her now stable, previously "free spirited" relationship, loving mother of three, fit body, still enjoys a party lovingly chaotic extended family persona, Angelina Jolie has her "intellectual", White paternalistic, "above, but a part of Hollywood, maybe not all the way tethered, but heart's in the right place, inner Punk Rock, sexy bisexual, kissed her brother, always wearing some Legacy design house clothes" persona.
Gwyneth Paltrow has her "broadly and deeply connected in Hollywood and the fashion world, was a fashion icon BEFORE one needed a stylist, doesn't pretend to be " down" , yet will have the rapper Nas defending her if needs be, genuinely worldly, bicoastal, bi cultural, gentile/ Jewish , a little kooky, still smokes the odd cigarette, can't dance, but works out persona.....etc, etc.
The ability to hustle, diversify and WORK are other very important elements. Stagnation and a lack of curiousity are not options. Martha Stewart and Snoop Dogg are friends, for example. The Obamas have Erykah Badu come to their shindigs. The parochial with a touch of coffee life of Meghan Markle is going to need to loosen up in order to seem long term aspirational, thus sellable.
What is her persona? Can she thicken her skin? Can she graft like a coal miner? Can she be " authentic" in a way that people can be convinced that right or wrong , that is the real deal trying to flog those wares?
Every single person that I have mentioned other than Meghan Markle have endured being slagged off longer or as intensely as Meghan Markle, but their personas are not tied to victimhood or moral crusader. That goes even for Barack Obama and he's an ex two term president!
When Meghan can translate even herself outside of the two dimension paradigm that her image currently resides in .....and she'll have to relax her backbone some to do that and accept her global fame comes as a " wife of" with more humour than is currently apparent.
Either she uses her brittleness as a marketing ruse, thus having to give far less of a fuck about public censure or lose the brittleness, thus giving far less of a fuck about public validation.
That and the ability to co operate will stand her in good stead, but she won't reach the status of any of the above before putting the work in, no matter her current celebrity.
She also has to gain more interesting friends who she seems to have real , non transactional relationships with. Glimpses into one's life sells a brand even for the most above it all celebrity seller.
Angelina Jolie is hardly papped not holding hands with one of her up in age children.
