Yes, it's true, GPS lingerie has been introduced by Brazilian Lucia Lorio, who says her dainty garments are for the "modern, techno-savvy woman." This follows a great tradition of adding all sorts of odd technology to underwear.

But, maybe these are really for insecure husbands and boyfriends who want to keep track of their gals? That's the argument raised by some women who say the new underwear amounts to nothing more than a modern-day chastity belt. (Question: Does adding a GPS unit to any item instantly make that item more ... GPSey? Discuss amongst yourselves.)
