How to use: Just put on your 'Soul of the Blue' t-shirt and show off your style! Whether you're going out for a casual day or relaxing at home, these shirts are perfect. Size selection: Check the size chart carefully to pick the right fit. The regular t-shirts go from S to 4XL, and the premium ones from S to 3XL. Care tips: Machine wash in cold water, turn the shirt inside out and wash with similar colors. Only use non - chlorine bleach when it's really dirty. Hang dry after washing for the best look, but you can also tumble dry on a cool or low - heat setting. Things to avoid: Don't use fabric softener as it can make the colors fade. Also, don't iron or dry clean these shirts to keep them in good condition.
