Seems like these are the type jammies y'all would get for Christmas :
Clothing brand Lauren Scott is introducing a new line of sleepwear (aka jammies) that come embedded with RFID tags so that you can be instantly alerted if their spouses try to sneak out for a night of wild partying. The clothes will be sold at Target and work with SmartWear's RFID system of tag readers that you're supposed to place near doors and windows.
