Studio 5050's Embrace Me hoodies are marked with bold abstract pattern (the collection's logo) made up of a silver conductive fabric. In order to light up, two people must be wearing the same type of jackets. When they hug each other, they actually power up little lights at the back of the garment. The lights flicker in the shape of the Big Dipper star system. A tiny heart beat sound can also be heard. Two hearts beating as one?
The hoodies are soft dark blue canvas and mad of 100% bamboo basket weave. The catch is, you have to buy two of them. They cost $480-$600 for the pair.
