People are more expressive through the shirts they wear. They may not be vocal but if you see them wear shirts with a particular message, more often than not, it is what they mean. Do not be all too serious, though, especially when some are meant to be jokes. Many civic groups and organizations can send their message across especially when many of them wear it on the same day. It is also a good idea to have it as the wedding souvenir of a couple. A gift for mom and dad on their anniversary will be great too. Custom design t-shirts are swell!
