Her sense of style doesn't have to improve per se, she just needs to hire a stylist. Many other do it why can't she? She can surely afford it. Look at early photos of Rosie HW, she was a walking mess. But now, after years of having a stylist and working on herself she kills it wherever she goes. Seems that problem with Adri is that she doesn't want to improve. Or even worse, maybe she thinks that she has a great sense of style.
