The square neckline provides a crisp, architectural frame for the collarbone, while the smocked back is the real hero—it ensures a secure, "painted-on" fit that moves with you and accommodates different bust sizes comfortably. With its tailored front and slightly cropped or hip-length silhouette, the Kylie top is designed to look just as good tucked into high-waisted trousers as it does worn loose over denim.
