To wear this Fiona shirt, you can simply button it up and wear it solo for a cool summer look. If it's a bit cooler, layer it under a light cardigan or a denim jacket. When washing, use a gentle cycle with cold water to keep the cotton fabric in good shape. Avoid using harsh detergents as they might damage the shirt. After washing, lay it flat to dry to prevent shrinking. Iron it on a low - heat setting if needed, and it'll be ready for your next stylish outing.
