- Cut your skirt hem shorter based on your preference. Most Catholic schools limit uniform hems to below the knee. Hem the skirt with a sewing machine to keep it from fraying.
- Take the bottom front of the button down shirt and tie the two sides into a knot. How high you tie the knot depends on your preference. You can secure the knot with a safety pin to ensure that it stays intact. You also can modify the shirt by cutting the sleeves shorter or off.
- If the uniform comes with a neck tie, add it around your neck or tie it around your waist. Complete the sexy girl look by adding knee-high stockings with heels or knee-high boots. Other details include wearing nonprescription glasses and styling your hair in pigtails.
