A fully backless dress requires confidence because there is nowhere to hide. The entire back is exposed from the neckline downward which makes this the ultimate statement piece. This works best when the dress is otherwise relatively simple because the backlessness is doing all the work. The construction needs to be impeccable because there is no back seam to hide mistakes. These dresses typically require a specially designed bra or no bra at all which is a practical consideration. The impact is significant and immediate. These are the fully backless dresses that work for someone who is clear about what they are communicating through their clothing.
