The fit-and-flare wedding dress.

The key difference is where the skirt begins to flare. A fit-and-flare releases at or just above the knee, which frees the upper leg and allows a normal walking stride. A mermaid holds the body through the mid-to-lower thigh and flares below the knee, creating a more constricted movement.

Visually, the two silhouettes look similar in a still photograph. The difference is most apparent when you are walking — and most notable after four hours at a reception.

A fit-and-flare is often described as the "wearable mermaid" because it offers most of the visual drama without the practical limitations.

The fit-and-flare works for brides who want to define their waist and hips but do not want to feel restricted in the legs. It has a forgiving flare point — because the skirt opens before the thigh, brides with fuller hips often find the fit-and-flare more comfortable than a true mermaid.

The silhouette photographs beautifully from behind when paired with a dramatic train. The combination of the fitted hip and the wide skirt sweep creates a distinctive shape in profile shots.

Brides who are unsure between an A-line and a mermaid almost always try a fit-and-flare at some point in their appointment. In the fitting room, the difference from both becomes immediately clear.

The fit-and-flare is more fabric-flexible than a mermaid because the flare begins earlier and does not require the fabric to hold through the full length of the thigh.

Lace — particularly corded and beaded lace — is one of the most popular choices because it gives texture to the fitted bodice and transitions naturally into the flared skirt. Enzoani and Kitty Chen both offer fit-and-flare styles in lace that have become consistently popular at Boulevard Bride.

Tulle skirts over a fitted lace or crepe bodice give the silhouette a romantic, lighter quality. The tulle flare adds drama without the weight of a heavily structured fabric.

Crepe and liquid crepe work well for sleek, modern interpretations. Madi Lane uses liquid crepe in their fit-and-flare styles, producing a gown that moves fluidly and photographs cleanly in both indoor and outdoor settings.

The fit-and-flare is the most venue-flexible of the body-conscious silhouettes. It is wearable outdoors — the flare begins early enough to allow movement on uneven terrain — and formal enough for black-tie events.

Train length is worth thinking about. A cathedral train on a fit-and-flare reads very formal and photographs dramatically in large venues. For an outdoor ceremony or a casual reception, a chapel or court train keeps the look elegant without the impracticality of full-length trailing fabric.

Accessories pair easily. A belt at the waist reinforces the fitted hip. A long veil echoes the drama of the skirt shape without competing with it.
