April's thread about ultra-casual clothing had me thinking about the influence of male fashion (or SO fashion) on women's fashion on the street, and whether casual male dress influences the degree to which women dress casually or dressily. For instance, in academia, I've seen male professors wear blue jeans (not the dressy kind), with t-shirts, or blazers and jeans. To my eye, it looks extremely unprofessional, but it also has the effect of making 'dressy' outfits appear even more dressy. When you're surrounded with casual male dress at work and at home (especially if your SO prefers t-shirts and jogging pants), does that influence your own sartorial choices and if so, how?
