Jill’s outfits

I’m not sure if it’s a production choice, budget constraints or laziness but I think it’s weird that Jill’s whole persona is a rich woman who loves shopping, Neiman Marcus, has a huge wardrobe etc but literally just wears a plain sweater, black trousers and flats all the time? There’s one wraparound sweater that she has in five different colours. Where’s the glam??
