Combining fashion with function, it’s no wonder Guess' men's shirts are so covetable. Guess uses only high quality materials for its shirts, such as denim, ensuring each piece looks as good as it feels. Guess' shirts are a worthy investment, which will work for both casual and formal occasions. There's a reason Guess' men's shirts are so covetable! By taking time to care for your denim, you’ll ensure your item stays beautiful for years to come. Before attempting to clean denim, we would always recommend checking the care label inside your garment before attempting to clean. Proper care will easily extend the life of your denim. To maintain fit, shape and colour, we advise washing every three to five wears. Use a mild detergent with cold water on a gentle cycle, and wash inside out to prevent abrasion and increase colour longevity. To ensure it retains its shape, always air dry and never tumble dry. The best way to store denim is to hang from the back belt loops, which will reduce any unwanted creases or stretching of the material.
