How to use these clothes is pretty straightforward - just put them on your little ones! For the youth T-shirts, they're great for everyday wear. The infant/toddler T-shirts and onesies are perfect for babies. When it comes to washing, always use cold water and turn the clothes inside out. Wash them with similar colors. Only use non - chlorine bleach if really necessary. Hanging them to dry is the best way, but you can also use a tumble dryer on a cool or low - heat setting. Remember, fabric softener can make the colors fade, so skip it. And never iron or dry clean these items. Also, for the infant products, check the CPSIA tracking label for any additional information.
