I don't agree. It's obvious that Orgetorix likes what he wears, and it never feels constricted or boring (as I guess the term "uniform" would suggest). Also, let's not comment on peoples weight, this is a clothing forum not jennycraig.com. IMHO a good tailor doesn't hide a person, he flatters his best features.
The suit is most flattering to a lean figure, it's just true. A guy like in stitches, someone who knows how to dress, would look better if a little leaner. Ogretrix, on the other hand, is bad with colors and has cheapish looking suits.
As for the jennycraig comment, look to the avatar...Gibson don't care, Mel wants war
