Where can I find/describe this silky robe from Gossip Girl? Have you seen any before and where? - lounging robe

Who knows what it is exactly this type of clothing, so it is called? I saw later in the episode Wild Brunch Gossip Girl, and Sharon Stone in Catwoman also a while in his vanity. I think they are dressed in silk, but when I saw with "silk dress" or something similar, I have something else. I think you have a specific name or style of them. I know that many women have during the rest periods in the morning or late at night or during the placing on the makeup used. They are very silky and long and flows that seem to touch the ground, while with high heels as in the pictures below. Who knows what they are looking where they are sold, or how you describe it?
