The suit in that photo screams Hardy Amies.
Regarding your concerns, to avoid looking like some anonymous young banker from the late 1990s, or Tony Blair from any period, you need the hard-core torso shaping and a non-intuitive patterned cloth.
EDIT: Also, to wear this you need to be tall and rake thin. If I remember correctly from past photos, you (Yachtie) are sturdily built, so my sense it this style probably won't work for you.
