I would love to see this jewelry set available in the Sims 3. I imagine the hair thing would have to be a hairstyle with accessories (like a hat or something). I don’t know what to call all of the bands and strings going all over the hair, but I know the part hanging over the forehead is called maang tikka (or maang tikka). The jewelry on the hands are hathphool (also called haathphool).
Also according to that page, this picture shows a lovely maang tikka which is the “smaller” variant of the shringaar patti, having only the central piece on the parting of the hair with the tikka hanging down the forehead.
