These men's casual shirts are easy to wear. Just pull them on over your head. They're perfect for summer days, whether you're going out with friends or running errands. When choosing a size, remember to check the size chart carefully. Since they're made of cotton, they're breathable but may shrink a bit if washed in hot water. So, it's best to wash them in cold water and hang them to dry. Iron on a low - heat setting if needed. Enjoy wearing these stylish shirts with stars print and geometric patterns all summer long!
