It's supermodel and fashion designer versus reality TV star and new author!
It's The Hills Lauren Conrad vs the designer Kate Moss in who wore it best!
When Kate Moss flew across the pond to help launch the Manhattan Topshop flagship store she wore a dress from her own Topshop collection.
She wore a smart black blazer and black tights to keep warm in the nippy New York air...
Lauren also wore a blazer but this time a more summery grey version, she had her legs bare with metallic peep toe shoe and an oversized black clutch...
And the best thing about the dress is that you can buy it yourself if you like it! Then you can do who wore it best with yourself and Lauren or Kate! Pick up your dress from Topshop for £65
So you've got lots to tell us! Firstly who do you think wore it best and also whether you love or loathe the Topshop dress! We think it looks a lot nicer on!
