When considering the trend of suits in the 1970's, you have to consider the disco revolution. Flared trousers were the rage, and leisurely suits common. The 3 piece suit was the most apparant, with wide lapels that mimicked their matching trouser flares. Shoulders were sharp and sleeves seemed to carry more space. Overall, the suit doesnt hug the body like it once did. there seems to be more movement, in examples such as that found in the image, right.
