Wardrobe malfunction or fashion statement? That's what Brazilians were left wondering Thursday, a day after top model Naomi Campbell (search) paraded with her breasts bared at Fashion Rio (search) — a weeklong event of fall/winter collections, which ends Friday.

Campbell kicked off the fashion show for the TNG label in a simple white flower print dress, topped with a white mink stole.

But less than halfway down the runway, the sleeveless deep V-neck dress proved more revealing than perhaps designer Tito Bessa (search) had intended. It wasn't clear if a strap or button had come undone or whether it simply fit Campbell loosely.

Following the fashion show, neither Campbell nor Bessa were talking.

"The people (in Brazil) are happy, I have great friends and the clothes make me look younger, too," was all Campbell, 34, had to say.

In recent years, Campbell has been a frequent visitor to Brazil, parading at the Rio and Sao Paulo fashion shows. She spent New Year's at a fashionable island resort at Angra dos Reis.

After the show, Campbell said she was heading back to New York to promote a movie, whose name escaped her.

Campbell was joined by Brazilian top models Isabelli Fontana, Mariana Weickert, Caroline Riberio and Ana Claudia Michels participated in the TNG show.
