Booby Tape co-founders Bianca and Bridgett Roccisano are self-made millionaires thanks to their genius invention of “breast lift in a box”.

And on Tuesday, the glamorous sisters enjoyed a well-deserved shopping spree on one of Milan’s most expensive and exclusive streets, Via Monte Napoleone.

Bianca, 34, and Bridgett, 30, who also have their own clothing label, cut stylish figures as they stepped out in the Italian city.

Bianca looked chic in a black long sleeve top and high waisted jeans, which she paired with a long faux leather jacket.

The brunette beauty paired the look with a pair of combat boots and a black Hermès Kelly bag and oversized dark sunglasses.

Meanwhile, Bridgett, who recently got engaged to partner Joshua Cavallaro, looked edgy in a pair of black jeans, Nike trainers and an oversized emblazoned jacket.

Bianca and Bridgett are co-founders of the eponymous clothing brand Bianca and Bridgett and beauty brand Booby Tape – which has been described as a “boob lift in a box”.

The Victorian sisters now sell Booby Tape products in over 35 countries.

Their standard chest band, launched in 2018, sells for $21.95. One of their latest products sold out in just 24 hours.

The women previously told Daily Mail Australia they had noticed there was a gap in the market for products focused on supporting women’s breasts.

“It’s been crazy; we have been overwhelmed with the global response and support we have received from customers,” said Bianca.

“We thought the business had potential from the start, but we didn’t expect it to grow so quickly.”

The brand has over 1,000 dealers in Australia, America, China and the UK.

Speaking to Forbes about building their multi-million dollar business, Bianca said they started with just $15,000, which came from their fashion line.

“We started the business with $15,000 – $1,000 of which we spent on a photo shoot,” she said.

“Even though we only had a small product at the time, our philosophy was that if we wanted to be a multi-million dollar global brand, we had to love one.”

“It’s an Australian born company and we started this. And because of the branding and marketing – which we’re heavily involved with – it feels like a global brand.
