Not one who's dedicated to the job like AK for Liz, but her staff is responsible for clothes like AK, it was one of her assistants, the blonde woman, I forgot her name (Natasha?). I think it's the same woman who married the royal photorapher Jackson and quit when she was pregnant.
She was an "assistant" and that's the job title of the dresser.
Their staff is mostly around their own age.
Ultimately it doesn't matter whether you have a stylist, because the stylist goes by your taste and objective and yours is the final approval.
Sure, sometimes they suggest something a client agrees to and regrets, so sometimes the "blame" lies with the stylist, but ultimately it's the wearer who consents.
I agree that the coat would've looked better with navy blue accessories and it would've mirrored the logo of the NHS, but overall I liked the coat tbh. A bit too white, but ok.
