Good news, these cult jeans Margot Robbie loves are on sale for Prime Day.

The only thing better than finding your perfect pair of jeans is finding your perfect pair of jeans on sale. 

And I've done the hard work for you, people. 

Margot Robbie's go-to pair of Levi's 501s are discounted during Amazon's Prime Day sales (and it wraps up on Sunday so you'll need to move quick!)
