This is mostly curiosity on my part but I was reading Mo's thread about purchasing a suit and am a bit confused as to why separates are more versatile than a suit. The way I see it, the suit can be worn together as a matching suit for the more formal events/occasions or it can be split apart and worn with the pieces that would comprise the separates equivalent, i.e., grey suit jacket with navy or brown pants or grey suit pants with navy or brown jacket. The separates can be worn with other separates but will never be a suit. Doesn't this make the suit more versatile as it does everything the separates do but with the added feature of being a suit?

Perhaps I am misunderstanding the definition of separates but I assumed that it was the pieces that normally are a suit but in different brand, fabric, color, etc.
