A girl in a white shirt and denim skirt.

I'd rate this outfit an 8 out of 10. The combination of a crisp white button-down shirt with a denim skirt is a timeless, classic look. The white shirt is versatile and looks fresh, providing a clean contrast with the blue denim. The fit of the shirt is relaxed yet tidy, while the rolled-up sleeves add a casual touch. The denim skirt offers a classic and youthful vibe, and its high-waisted style complements the tucked-in shirt. This outfit strikes a nice balance between casual and put-together, suitable for a variety of daytime activities. To elevate the look, consider adding one or two accessories, such as a statement necklace or a belt. Adding some color through shoes or a bag could also enhance the overall style.
