A retailer is selling three pairs of jeans every minute as they clear out $20 million worth of stock.

More than 53,000 pairs of jeans have flown off the shelves as customers flock to Jeanswest stores before doors close for good.

The company is shifting to an online-only platform and closing its bricks-and-mortar stores after entering voluntary administration in March.

Since then, a fire sale to offload existing stock has drawn hordes of customers in, with jeans selling at a rate of almost three per minute, administrators Pitcher Partners said in a media release.

A total of 160,000 items have been sold, with 184,000 customers visiting stores and more than 540,000 jumping on the Jeanswest website.

Discounts are set to continue in the coming weeks as administrators look to shift more than $20 million worth of stock.

The physical stores will all remain open as the sale continues.
