Clad in the latest designer outfits and accessories, when a hero/heroine turns up for a film promotional event, the look indeed is put together by a stylist.
The stylists don’t get paid for travelling, sourcing and returning the stuff to the designer in good condition — we’re talking about stylists working for actresses here.
The stylists hope that their work will be noticed someday and the star will offer them a promotional event, if not a film for personal styling; but neither of that happens.
Interestingly, heroes pay their stylists or get the producers to pay. Not just stars but even the upcoming heroes do throw tantrums and make the producers pay for their personal expenses.
