The 70s: glam at its finest! Disco balls, flashing lights and plenty of awesome clothing helped to define one of the most exciting decades of the 20th century. These days, many of those trends are making a comeback, by way of Paris Hilton's feathered blonde locks that often closely resemble the hair of legendary starlet Farrah Fawcett. Another example are the high-waist pants that are making their way into the closets of fashionistas like Penelope Cruz, often sported by Janis Joplin, among other pop-culture mavens. From floral patterns to flare-leg denim, the style of the 70s is definitely stayin' alive.
