Welcome to the Brides Fashion Friday fix!

Rex Features

Every Friday we select one celebrity look from that week and pose the question: Would you wear it to a wedding?

Is it fitting for a bride, worthy of a bridesmaid or made for a guest? What makes it wedding-worthy (or not) in your eyes?

This week we've chosen Keira Knightley's romantic Mary Katrantzou strapless dress which she wore to attend the Can A Song Save Your Life? premier in Toronto this week. 

Matched with killer Christian Louboutin heels, the actress undoubtedly looked beautiful, but we want to know: Would you wear it to a wedding?
