An oversized square sunglasses shape is unquestionably making a statement which is the entire appeal. The geometric intensity of the shape needs confidence to carry off which is precisely why you should buy them if you want to actually wear them. The lens should be truly substantial and the frame should feel solid rather than floppy or undersized relative to the lens. Acetate construction tends to feel more intentional than metal at this scale and colors should be either classic black and tortoiseshell or genuinely committed to something bolder. Fit matters because oversized frames that slip down or pinch at the temples stop being fun immediately. These are the oversized square sunglasses for people who want their eyewear to actually be visible.
