To use this T-shirt, simply put it on like any other shirt. It's great for everyday wear. When it comes to maintenance, remember not to dry clean, iron, bleach, or tumble dry it. Instead, use low heat. For washing, put it in the machine with cold water (max 30C or 90F) and set it on a gentle cycle. Also, be aware that the preview images might look a bit different in color from the real T-shirt because of the lighting when we took the photos or how your monitor shows colors.
