I ordered two Signature Production DUI suits back in August, one for myself and one for my SO. It took about a month a half for them to get the final product back to us. Except for the sleeve length, my SO's suit fit her pretty much perfectly out of the box.
Unforutunately, I had more than a few problems with my suit. The main on ebeing that I had to struggle to get it on and off, since it was a few inches too short. Called up DUI, gave them some modified measurements, and they had us ship the suits back to them on their dime. They said they would fabricate a completely new suit for me.
Three weeks later, second time around, my SOs suit is now perfect since they trimmed the sleeves. My suit was much easier to don and doff, but it was really baggy up top. Called them up again, and they apologized for the fit, and said they would try to make it right the third time around.
Again, they paid for shipping back to them and did not charge us for any alterterations or rebuilding of the suit. Hopefully, the third time is the charm. So, I can honestly say that when you pay for a Signature Production suit, DUI will do whatever it takes to get it right.
Sorry it was a little lengthy, but I hope you found some answers you were looking for.
