The $28 Tata Top is a bikini top with nipples situated to suggest that the wearer is topless (should the wearer have skin color that matches the top, of course!). It's a pretty effective illusion, at least for the model used in the publicity photos, and the maker suggests it's a way to challenge discriminatory laws that hold that bare chested women in public are damaging to the social fabric, while men are able to wear as much or as little above the waist as they choose.
