I do honestly I dress nicely by choice - I work from home and can wear what I like but I choose to wear a tie everyday. Liverano and rubinacci both seem to me to be very comfortable and relaxed clothing - more suitable for my lifestyle than the likes of Anderson a Sheppard etc. I don't want to look like Gordon Gecko / I want to look like I belong in a jacket and tie and feel comfortable so doing.
The Anderson and Sheppard cut is considered "London Drape" and has extra folds of cloth in the chest ("drape") and very soft shoulders. I haven't heard A&S suits called anything but "comfortable and relaxed." The iGent blogosphere often quotes Fred Astaire as saying that he did all of his dancing in A&S suits.
Also, the house cuts Rubinacci and many other Neapolitan tailors are very similar style to Anderson and Sheppard. They are all descended from Frederick Scholte and his famous "London Drape."
