There's no denying it: little black dresses are and always will be a wardrobe staple. However, Kate Hudson just made an argument for swapping mini-length styles for the equally versatile black maxi dress.

Her exact Alaïa gown has a budget-bending price tag of $3,150, but we found a style on Amazon that closely resembles the look for a fraction of the cost.
