Update to my situation. I tried on the extra slim fit dress shirt at Brooks Brothers and it was still too baggy on me. My chest and shoulders are very big relative to my waist. I have literally tried on over a dozen shirts from multiple stores. I went into both Ralph Lauren and Brooks Brothers and asked for their slimmest dress shirt, but once I put on the 17 neck the shirts are huge on me. On a side note - the Ralph Lauren shirt I tried on was $400 (I never would have paid it even if it fit) - I don't understand how they get off charging so much. It really didnt seem like anything special.
I may have potentially found a decent option from Nordstrom though. I tried on their house brand french cuff shirt in the non-slim model. It really wasnt a bad fit at all for being. Still too baggy on me, but I am hopeful that if I can order the slim fit - it could be a great fit. Only draw back is that is it is a very wide spread collar - which I don't love, but for one shirt, I can accept it. If I like it, Nordstrom has a design your own, so I may end up doing that as well.
If that doesnt work, I am giving up and going MTO.
