Silhouette refers to the overall cut of a gown. It's the most vital element to focus on, because a gown's shape is its foundation  - it's what sets the mood for the entire garment.  The fitted bodice and full bell-shaped skirt of the ball gown, for example, gives a princess-like presence. More form-fitting styles, like the A-line and sheath, offer a different appeal. The A-line elongates the line of the body, adding the sheath ups the ante on wedding-dress sex appeal, creating a sleek and modern option for the more daring.  While the sheath ups the ante on wedding-dress sex appeal, creating a sleek and modern option for the more daring bride.

The Ball Gown

The most traditional of all shapes, the ball gown is typified by a fitted bodice and natural or dropped waistline that leads to a very full skirt.  Pleats or gathers in the the skirt are what make it a ball gown.

GOOD FOR: skinny minnies (adds curves) and pear shapes (the skirt hides everything).

BAD FOR: the petite (the excess fabric can overwhelm tiny frames) and those with a lot on top (you might end up looking round)

The Sheath

A modern sexier take on the traditional wedding gown, the sheath is characterised by a slim profile that closely follows the curves of the body.   This style is characterized by a low waistline that is generally V or U-shaped, beginning several inches below the waist. Petite brides may want to consider other shapes as this style may create a shorter appearance. 

GOOD FOR: the tall and thin as well as the slim and petite (the lean shape adds length). This shape is great for taller brides who are looking to create an hourglass appearance with the low waistline.  Recommended for: taller brides, large hips, hourglass, pear shape figure.

BAD FOR: anyone who feels like they have something to hide    (we repeat: lean shape).   Not recommended for: petite brides

The A-line 

As its name implies, the A-line cut is narrow at the top, cut close to the ribcage, and extends out along the body in the shape of a triangle (or 'A') in a smooth, elongated line. It is perhaps the most popular skirt option, as it looks wonderful on a variety of body types. The lines of the skirt are always clean and ungathered, but there is, as always, a number of versions. The princess cut is exemplified by vertical seams travelling from the bust to the hem.  Another take is the circle skirt, a very wide A-line with a full skirt.
