To wear this blue linen shirt, you can button it up all the way for a more formal look, or leave a few buttons undone for a casual vibe. You can tuck it into your pants or skirts, or wear it loose over leggings. When it comes to care, machine - wash it in cold water with like colors to keep the color and fabric in good condition. Avoid using bleach as it can damage the linen. Hang it to dry to prevent shrinking. Iron it on a low - heat setting while it's still a bit damp for the best results.
