Hey guys- purchased this OTR suit in a major bind in November '15. Turns out I didn't need it, but kept and tried it on in apartment a few times subsequently and decided it wasn't for me. Since I waited too long to return, here we are... 95% wool, 5% mohair navy fabric for both jacket and slacks. I didn't alter a thing from the moment it was taken from the store. Happy to provide measurements and answer any questions. This could be a great suit for somebody to tailor a bit and kick around in without worrying about how expensive it was.
