In 2024, the best sunglasses shapes for different face types focus on enhancing natural features. For round faces, square or rectangular frames add angles, while oval faces suit nearly any style, especially aviators and cat-eye shapes. Square faces benefit from round or oval frames that soften strong jawlines, and heart-shaped faces look great with cat-eye or top-heavy frames to balance the forehead. Oval and oversized frames work well on oblong faces, adding width for a balanced look. This year’s trendy materials like acetate and double-bar designs make these classic shapes even more stylish.
