British designer Jenny Tillotson has developed a line of multi-sensorial clothing that acts as a "Smart Second Skin". The fabric interacts with the human emotions of its wearer and releases a selection of scents based on your mood.
As much of the research in Smart Second Skin clothing includes work with pheromones—the aromatic molecules, which smell musky when we are sexually aroused and are found on our skin, the lab is working on sensors in garments that could be programmed to detect someone whose pheromone profile is of interest to you and send them a sample of your own pheromones.
I'm not sure how receptive I'm going to be to a sample of anyone's pheromones, personally, but to each their own. Regarding the picture, I'm assuming that's a conceptual mockup and not, you know, a working model.
