An oval beehive do

Does anybody know how to put up their hair in a beehive style - the kind that looks oval and pointed to a 45 degree? I've seen newsreaders sporting it, and what's curious is, some of them only have shorter than shoulder length hair and seemingly quite fine and thin hair. I wonder if the hairstylists use a bun ring or some prop to make up for the volume on top. I am guessing the hair is all tied up high on the head and pushed up to get the height. Can someone tell how this do is done? It isn't a bun hairstyle, more like a wrap-around thingy from what I observe.
