To wear this Eileen white cotton shirt, you can simply button it up and tuck it into your jeans or skirts for a casual or semi - formal look. You can also leave it untucked and layer it over a tank top. When it comes to care, machine wash it in cold water on a gentle cycle. Use a mild detergent. Avoid using bleach as it may damage the cotton. After washing, tumble dry on low heat or hang it to dry to maintain its shape. Iron on a low - heat setting if needed.
