I agree with you if we are talking about the impact RL has had as a lifestyle brand. But if we are talking purely about tailored clothing i would have to argue for Brioni. Majority of the suits out there today are based on a cut (Continental Cut) that they invented, and they have consistently have had very high standards when it comes to fabric and quality level from their founding all the way till today. But if we are talking lifestyle brand then of course Brioni would lose out to RL. Edit: Was looking for this quote by Jay Mclnerney "Today, devotees of the subtle luxury of Brioni are as likely to be heads of state, diplomats, and stylish CEOs as movie stars, Still any male who has ever fantasized about being an international bon vivant aboard a yacht or in a convertible sportscar is probably picturing himself, whether he knows it or not, dressed in Brioni" That pretty much sums up why i think Brioni should be on the list, and high up on it as well.
