The 1950's brought a rebellious youth revolution in which icons such as Marlon Brando gave denim, and in particular the 501 jeans, iconic status.
In the mid 1950's Levi Strauss & CO. became a national phenomenon. In order to make potential consumers comfortable with the companies products, LS&CO. introduced a zipper version of the button fly Shrink-to-fit jeans in 1954: the 501Z. It had everything longtime wearers loved: the silhouette, the tough but flexible fabric, rivets etc. Retailers carried both the 501 and its zipped brother, the 501Z, and everyone got the pair of Levi's jeans that worked for them.
