If you want to change your sim’s hairstyle for different outfits, be sure to unlock the hairstyle by clicking on the small lock in the top right corner. You can select from one of these eye colors, or you can create a custom color using this color wheel: The slider on the bottom adjusts the brightness of the color wheel. When you select eye color, you can either select one of the given eye colors, or you can create your own by clicking on the paintbrush “create a style” button. How do you create your own style in Sims 3?
