Fashion historian Caroline Weber came to Big Think yesterday in a beautiful Marc Jacobs dress. The significance of her outfit? Shoulder pads, or as she calls them, an 80s-era fad that's back and better than ever. She said: "We’re living in a moment when fashion designers don’t have time to understand or to think about the history of what they’re doing. They throw in some 80’s because they just did the 70’s a few weeks ago, and the 60’s are coming back tomorrow because the 80’s are about to be over and we need to keep selling more clothes."
