There seems to be a bit of paranoia here regarding striped shirts these days, which I suspect is partly fallout from a recent exchange on the so-called “Good Taste” thread. To be honest, most recent examples in this thread, such as Stiches’, all look good to me.
As a man who wears solid navy and charcoal suits quite regularly, I often rely on striped shirts to soften what might otherwise be a too severe look. It depends on the occasion. And I’m not convinced by the symmetry argument advanced on that other thread, by the way. YMMV, of course.
