Welcome to the Brides Fashion Friday fix!

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 Sienna Miller's white Michael Kors Collection dress, which she wore to attend Eve Cavalli's birthday party in London earlier this week.

We love the carefree boho peasant-style dress with its peekaboo lace details, but we want to know: Would you wear it to a wedding?
