This shirt is super easy to wear. You can put it on for work during the day and then keep it on for a casual dinner at night. It goes great with jeans and sneakers. When it comes to washing, you can machine wash it on a gentle cycle with cold water. Use a mild detergent to keep the colors bright and the fabric soft. After washing, don't wring it out. Just lay it flat to dry. When choosing a size, make sure to check the size chart carefully as different suppliers may have different measurements. If you're in between sizes, it's usually better to go for the larger one for a more comfortable fit.
