The word closet doesn't really accurately describe what you see above. These are more like fully decorated rooms with gorgeous pieces of clothing and a ridiculous amount of shoes. And yes, I'd looooove to have one! A fireplace ... in the closet! This is where the women will be hanging out while the guys are in their mancave. The wallpaper, the wooden hangers, the art, just lovely.
