"A Look Back" is a daily column that highlights a moment from fashion's fabulous past. Today's pick is of Agnetha Fältskog circa 1970.

The band's catchy disco songs not only earned them a spot on the Rock and Roll Hall of Fame, but also inspired the Broadway musical and subsequent film adaption "Mamma Mia." What do you think of the Swede's pre-ABBA look?
