Booby Tape co-founder Bianca Roccisano suffers a nip slip in $2,250 gold minidress at launch

Bianca Roccisano, co-founder of Booby Tape, showed herself bold when she joined her sister Bridgett at the launch of their breast tape in Berlin, Germany, on Wednesday.

Bianca, 37, slipped a pair of panties as she poured her curves into a stunning Alex Perry gold mini dress, worth $2,250.

Luckily for Bianca, she made good use of her own brand of nipple covers as she stepped out of her dress and saved herself the embarrassment of the cameras flashing.

Despite the fashion blunder, she looked good to trot as she joined her newlywed sister Bridgett at Fredericks cafe and bar for the exclusive event.

Her metallic dress had thin spaghetti straps and a ruffled design. She paired the look with a pair of gold strappy heels.

Bianca sported a deep golden brown color and wore her dark hair loose. Her bracelets and jewelery were from luxury brands such as Van Cleef & Arpels.

Her sister Bridgett, who married husband Joshua Cavallaro in Melbourne last month, looked chic in a plunging black mini dress, oversized blazer and heels.

The Roccisano sisters are co-founders of the eponymous clothing label Bianca and Bridgett and beauty brand Booby Tape, which has been described as a “breast lift in a box.”

Worn by Jennifer Lopez, among others, Booby Tape products are sold in more than 35 countries.

The pair, who started out as celebrity stylists in Melbourne in 2010, recently spoke to Daily Mail Australia about how they went from broke college students paying “$5 in fuel” a Volkswagen Jetta to becoming multimillionaires.

“We were totally broke,” says Bianca, who studied law at university.

“Bridgett and I sat down and I was like, ‘We’re not doing it anymore. We have to make a living. We don’t have any money, so what kind of business can we start?'”

Their business journey began with the launch of clothing label Bianca and Bridgett, followed by Booby Tape, which now has annual sales of $10 million.

Bridgett said the idea for Booby Tape came from the sisters being “both big-breasted women” who were sometimes forced to “restrict” their wardrobes.

“I remember going to the races for a year and I wanted to wear this low-cut backless dress and I couldn’t because it would make me wear a bra for support,” she said.

Bridgett started using electrical tape and duct tape before looking for a breast-specific tape, but realized there wasn’t one on the market.

“I jumped on the computer, searched it, and there was no such thing. Then Bianca was like, “I don’t believe that,” so we looked it over and decided something needs to be done,” she added.
