No idea, but I can tell that Gucci is authentic just from the labels there.
There is no way it is a fake unless the person was able to get original Gucci tags, and even so, he would need a suit maker who could perfectly replicate Gucci's signature suit style from 10 or so years ago.

10 or so years would put this suit in a period when Tom Ford was the Creative Director at Gucci. Right?
