The catchlights in her eyes are from a relatively small light source, but the shadows underneath most if her body indicate a much softer source at a lower angle above the camera's optical axis than the light seen in the catchlights.

Any time we talk about light sources being soft or hard, or large or small, what we are referring to is the angular size of the light as measured at the subject. Soft and large mean basically the same thing, as do hard and small. Take the sun, for instance. It is millions and millions of miles in diameter! Yet in terms of photography done here on Earth it is considered a small/hard light source because its angular size in the sky is only about 1/2º. That is why the sun throws very hard shadows. A hard shadow is one with a sharp, well defined edge. A soft shadow is one with a fuzzy edge that makes it hard to see exactly where the shadow ends. To use the sun to create softer light/shadows we put some sort of diffusing material between the sun and the subject so that the light falling on the subject comes from a wider angle than the 1/2º of direct sunlight. We may also use a flash illuminating the subject from another direction to fill in the shadows created by the larger light.

In the case of your example photo, it appears that a rather wide (but not tall) light source was angled from about 60º above the camera's optical axis. Perhaps a long, rectangular soft box. A brighter, smaller light appears to have been pointed at her face from just left and above the camera. Perhaps a beauty dish, possibly with a small diffuser. Notice the harder shadow cast by her nose and arm compared to the shadow cast by the rest of her body. It is likely there were screens placed to the left of the smaller light source to block the harder light from it from spilling into the rest of the frame.
