I have never seen a woman wear a belt in that way. I’ve never, that I recall, seen a woman wear a belt over a cardigan sweater. Clearly this is her “signature” piece, and her “unique” style, and we’re just going to be stuck with it, even though it’s both unflattering and stylistically idiotic.
I have seen teenage girls in similar belts. They general wear them low, below where their waist would be if they had a waist, around the top of their pants but not holding the pants up or anything ... just sitting there.
Yeah, a low-slung, sideways belt kind of 80’s style, yeah, but OVER the sweater, right up to the underwire? WEIRD.
