(CBS) No history of the Oscar ceremonies, which date back to the 1920s, is complete without a look at how red carpet trends have changed.
On Oscar red carpets you can always find tons of organza, lace and satin and mountains of diamonds and sapphires, but how those fabrics are draped and how those gems are worn has changed dramatically over the years.
And it's not just the gowns.
Those elbow-length white and black gloves you saw on starlets when TV first started broadcasting the ceremonies in the 1950s and 1960s are a thing of the past, except perhaps for Madonna and Lady Gaga.
So, too are the big bouffant hairstyles of the 1960s and the shags of the 1970s. Sleek is in these days.
