The centerpleat is pretty much a question of tradition as it is seen on nearly all OCBD's; yet for me I don't have them as said before (I believe) they dont provide function and they seem to make the line falling from my back swell and make me look fatter (main reason :P)
Alright, thanks for the input.
I will probably get one without center/box pleats. But plain back or shirring? Didn't find much info about shirring when searching for it online.
So for the next bunch of shirts, I will reduce the sleeve width slightly and get either a plain back or shirred back. Thinking of actually ordering a couple as the wait is probably the same anyhow.
