Corporate Portraits in London and a moire issue

I used a great studio recently in Holborn called Stu Stu Studio (great name) reasonable rates and friendly people. I shot a series of corporate portraits for one of my clients which looked great except for a few of the shots which were displaying horrendous patterns on the subjects suit, commonly known as moire. I asked several people how to get rid of the offending pattern, but eventually found a very good solution at a tutorial aptly named moire go away. Here are the before and after shots.
