Lingerie maker Lucia Iorio says her new design targets the modern, techno-savvy woman, but the GPS-equipped "Find Me If You Can" line has raised the hackles of feminists who call it a 21st-century chastity belt.

The lingerie combo consists of lace bodice, bikini bottom and faux pearl collar, with the GPS device visibly nestled in the see-through part of the bodice next to the waist.

"This collection ... is a wink to women and a challenge to men because, even if she gives him the password to her GPS, she can always turn it off," Iorio told AFP.
