What is your idea of doing business casual well? Does it entail using blazers/sportcoats often or always? I ask because I sometimes get frustrated with the business casual policy in my office. I sometimes wear a suit anyways -- usually without a tie -- just because. As for pure business casual days, I will go exclusively with wool slacks -- usually flat front, but a couple of pleated pair, usually in shade of grey 3 season weight flannel, some solid, but also houndstooth, glen plaid, windowpane, and (gasp) pinstripe. I will wear a dress shirt, always in a pattern (herringbone, fine pinstripes, sometimes a check pattern), mixing of barrell and french cuffs. I will often wear a fine gauge solid color wool sweater as well, usually in cashmere but sometimes merino wool. On some days I will opt for a zip or button neck sweater, but most days will go more traditional with a v-neck or crewneck. Of course, I use different shoes to mix things up. I make sure that my clothes fit and are (usually) pretty high quality (not Kiton quality, mind you), which to me are the two biggest problems with most business casual wardrobes. I don't have a single sportcoat suitable for work, because no one at my office wears them, and because I'm moving to a suits only office (sportcoats on Fridays maybe) fairly shortly. Still, I'd like to have one or two high quality blazers if I can pick them up cheaply. So, should I try to integrate sportcoats more into my wardrobe? I don't want to be the "guy in the blue blazer" mind you. But on the other hand, really cool odd jackets would stand out a bit much in the office here, I'd think. Am I doing all I can to get mileage out of business casual?
