I ordered a few of the dress shirts (15.5 x 33) online in white and yellow and received them yesterday. For some reason they don't stock the extra slims in the stores by me. Same with the "Milano Slim Fit Plain-Front Non-Iron Advantage Chino" which I have on the way to try out. The shirts are slimmer than their regular slim, which I found to be too baggy in the waist and arms on me. These extra slims fit a lot better on me. I can try and take measurements of these later this week.
