Interested in hearing the results from this as I am in the same exact business casual situation for this summer. I have 3 pairs of khakis and 2 pairs of wool pants. I think I am alright in the pants department, although I may want to add a few more pair of wool pants (one is navy and one is charcoal).
I think I need a few more shirts though. I have 1 lavender shirt with a spread collar, 1 blue and white striped shirt with a spread collar, 1 blue/white/green striped shirt with a button down collar, 1 red/white/blue checked shirt with a button down collar, 1 plain white shirt with french cuffs in a spread collar. I have one shirt on order from Jantzen, but that probably won't make it here for another month or so. I think I might try Ian at www.shopthefinest.com
and Stu from www.virtualclotheshorse.com
for a few more shirts before I start working next week.
As far as shoes, I have a pair of dainite-soled Polo brown suede chukkas, and a pair of brown Grenson cap toes from the first sale. I also have a pair of Loake black chelsea boots. I think I want to add another pair as well, I am trying to think about what to do here. I might check out the polo sale and see if I can add the Darltons to my wardrobe, or I might order a pair from Seok MTM (although this might take a bit too long), or I might try Stu again for a pair of the Certos that he has in brown suede (monk straps) or brown leather. I am also considering the Loake brown wingtips.
