This is Clara Peller, the "Where's the beef?" lady from the old Wendy's commercials.
These are bell-bottom trousers. They became fashionable for both men and women in the late 60's and well into the 70's. They were originally a functional part of a Navy uniform. The bell bottoms, just like other Navy apparel, were designed to be used as a flotation device in case of man overboard. the legs were tied and then flipped through the air to capture the air.
