This is a beautiful dress but if you have any hips at all you may find it difficult to find the right size. i usually wear a 0-2 p and found that that the op was too snug on the bottom while the 2p was too loose on top. ( for reference 32-26-35). so if you are perfectly proportioned it could work for you.
also, note that this is a pencil dress....very slim fitting.....probably best suited for a cocktail party.
