This garment called “Hidden” by the fashion design collaboration High Tea with Mrs. Woo, incorporates pockets that activate heat when the hands are placed in the pockets and the decorative cuffs come into contact with the pocket lining.  The materials in this garment include cotton, silk, polyester, conductive thread, nylon ripstop, copper PVC, hook and wire, and rechargeable battery. 

Other than this piece, their work doesn’t seem to involve any wearable technology but it is worth checking out their site for fun and if you like fashion.
