Female hobbits resemble the men of the Halfling race, but they are slightly paler and shorter. They also have small breasts. They still have the characteristic hairy feet of the hobbits.
Most hobbit females seemed to be honored and spirited housewives and in certain hobbit cultures, they had quite a bit of authority and status in their family and communities. In the extended family and community that Sméagol and Déagol lived in, their grandmother was a Matriarch and had the authority to expel Sméagol from the family when it became known what he had become.
