I think clothing whether cheap or not, as long as you know how to wear it you're golden! She looks amazing! I think the photo above the circle scarf reminds me a bit of Sasha Pivovarova rather than Poly.
But who says so many people cannot wear the same thing? I like her in black neutral clothes alot, but that outfit not so much. I see Agyness as a free-expressive-artistic vintage loving person. love the photo of her and her dog, amazing. personally something I'd wear!!
