Is a fit-and-flare silhouette the same as a mermaid?

Not quite. A fit-and-flare silhouette flares from around the upper thigh, giving more skirt movement and easier walking. A mermaid silhouette flares lower, usually from the knee, for a more dramatic body-hugging shape. Both silhouettes suit the sexy category, but fit-and-flare offers more comfort and movement across a long wedding day.
