This is quite correct-- even if the graphic is well-designed, as Gunnar's is, that doesn't mean that graphic t-shirts are fashionable. My opinion is that the larger the graphic on a t-shirt is, the less fashionable the t-shirt is. Wearing solid-color clothes is a great go-to option, though I bet that it would be possible to design shirts with less flashy graphics that could signal intelligence while still being fashionable.
