i'm aware of what you can purchase with the equivalent amount of cash, although having looked pretty intensively, i cannot find this exact fabric and what i want is this specific fabric.

@jamellebouie.net It’s still currently available to use on Suitsupply for custom. Can guarantee you it’s almost the same fabric. Only difference is a bit of stretch. But exact same texture.

Well I have one in 40R that I made custom through Suitsupply. It, admittedly, was a few years ago. Similar styling, except slightly wider lapel and double vent. I wear a 42 now, but it still fits. I can send pics if you are interested.
