Turns out sex always sells. Even in a pandemic.

Australian based international lingerie brand Honey Birdette has seen a huge increase in demand for their products, from sets to sex toys during the peak of COVID-19 lockdown restrictions.

Not only has the extraordinary jump in sales taken founder Eloise Monaghan by surprise, it's also been the change in trends with women choosing to splash out on coloured lingerie rather than the traditional black.

"If three years ago you would have told me I'd be doing lingerie sets in neon orange, I wouldn't have believed you," Ms Monaghan told The Daily Telegraph.

"But people's fashion habits have changed through this pandemic."

In the last three months, the brand's colourful Christine Neon collection has outperformed the previously best-selling Kukoru Black line by 40 per cent.

Accounting for the success, Ms Monaghan joked: "Everyone is bored at home. There is only so much Netflix you can watch."

Sexologist Dr Nikki Goldstein said she had seen a large spike in sales at her online adult store Dr Nikki Shop, especially large bundle orders.

"You do have couples who are at home saying let's experiment, but mostly a lot of people really struggling in relationships are thinking if they invest in the bedroom it'll help ease the stress on the relationship," she said.
