The sheath, or little black dress, now is one of the clothes that should never be lacking in the closet of a woman. Do you think that his fame has grown so much that the word little black dress has even entered the dictionary. Sheath which to choose? Each requires its own physical. If you have the sides a bit wider is better not to opt for dresses very close, too charming, and instead choose a model that enhances the waist and forms a soft caress. If you're skinny, do not choose models that will "flatten out" too.
