Fine, mostly all-one-length hair will appear fuller with some large, soft curls like Ginnifer Goodwin is displaying here. Locks should roll back along the front, then they can go in either direction along the sides and back allowing them to appear more natural.
Not long ago, it seems, Ginnifer Goodwin had her now bob style done in some growing out layers that was definitely considered short. It is now growing into a (borderline) typical medium bob style that requires little to no maintenance, even for an evening out, though you could apply some loose curls for a special occasion.
Bob haircuts have dwindled in popularity, yet as stated before, they never really go completely out of style as they are such a classic. Their ease in wear and maintenance makes them a favorite standby and as Ginnifer Goodwin demonstrates, they are quite complimenting as well.
