Poser Addicts had a dynamic shirt and a tunic for M4. Strangely, they even had a Men's shirt for Vicky and Aiko (royloo) but not a man's dress shirt for a man (M4)! I already had that shirt for Aiko by the way. Pity Karth didn't have one. I like the vendor personally and would have gladly parted with my shekels if he did.

In the end, It looks like I'll wait for either Sav or Sickleyield to have a sale as I blew a bulk of my budget this month and I like to have a reserve for the little things like food. Both would have to be retextured slightly for a dress shirt feel but even as they are, they both quite doable. For the record, I put in the term "M4 shirt" and I didn't see either of them. I just tried it again and there are all three shirts suggested to me. I have to stop drinking coffee so late at night.

My thanks to iceprincss2, male_M3dia and digitell. Your help was mucho appreciated!
