This dress is equal parts sexy because of the ruching and off shoulder, and relaxed, because it has no fastenings (super comfy) and is in a wearable fabric. Perfect day and evening dress. One thing to bear in mind is the ruching adds extra fabric to your sides, so adds to a curvy look.
This dress is the perfect LBD it can be pulled long to be knee length or ruffled up to be shorter. The style is flattering on all bodies due to the ruching.
