That silver scrunchie from H&M is such a vibe. Perfect for a sleek ponytail on a night out, or just to add a little something extra to a casual jeans-and-tee look. Looks cute with a messy bun too, especially for those days when there's no time to do hair but still want to look put together. Also works great as a wrist accessory to add a little metallic touch to an outfit.
