You've probably heard a lot about Black Friday and about Boxing Day. But, did you know that Singles' Day is actually the biggest shopping event in the world?

It's estimate that Singles' Day is actually four times bigger than Black Friday and last year a single retailer transacted over $38 billion on that one day.

Singles' Day occurs on November 11 and it's a shopping event of epic proportions. Here's everything you need to know. But if you just want to go straight to the sales - we've got a RUSSH-approved list running.

When is Singles' Day?

Singles' Day occurs on November 11 every year.

The date November 11 was chosen for it's numeric appearance 11/11 - a representation of the singles themselves.

What is Singles' Day?

Singles' Day is a shopping event that began in China that is now receiving increased attention in other parts of the world. It's a day when many big Chinese retailers and other brands offer discounts and sales in honour of being single.

Its origin comes from a Chinese university in the early 1990s. A group of students decided to start a celebration dedicated to being single. Since there are many events that celebrate people in relationships, like Valentine's Day for example, there was a feeling that there should be a day that devoted to celebrating - and destigmatising - those who are single.

The celebration started small but has grown in popularity and is now an unofficial holiday in China. People will hold parties to celebrate and many big retailers offer huge discounts and deals - especially big stores like Alibaba, Taobao and Tmall.

What can we expect from Singles' Day?

We can expect to see many sales, discounts and deals from stores internationally and locally. Of course, popular Chinese retailer Alibaba is renowned for having the biggest and best deals.

But expect to see plenty of other retailers join in. In the past we've seen Singles' Day sales across Jurlique and even Net-a-Porter. Last year we saw a fabulous designer sale across selected pieces at David Jones.

Where are the best sales at Singles' Day?

For designer fashion lovers, this is an event to be excited about. In the past Singles' Day has seen discounts of 15% or 20% on designer stores like Stylebop, Reebonz, Forzieri and even Net-a-Porter. There are many sales already live, you can see them all if you head to our RUSSH-approved list of Singles' Day Sales.
