The A-Line wedding dress baths in sophistication as it is conspicuous and long, flowing form from bust to hem and is a snug fit around a woman's bodice. The overall result is the silhouette of an uppercase letter 'A'. This classic, simple design is suitable for most occasions from garden gatherings to traditional church ceremonies.
The versatility of the shape of the A-line wedding dress allows it to accommodate various structural elements, which include skirts with contrasting fabrics, separate bodices or horizontal seams for waistline definition. Length is also a major factor. It has a varied knee-level form for the fun, flirty brides to full-length dresses flowing into chapel-length trains for traditional brides.
To achieve a vivid effect, choose the princess cut A-Line wedding dress. It emphasizes the A-line's clean lines by using vertical panels running all the way from neckline to hem. The elongated lines give the illusion of slimming. Moreover, the A-line easily supports various fabric choices, based on the desired look. 
For the simple look, the best option has to be free flowing, natural silk, for instance charmeuse. These fabrics allow dresses, to hang freely, bringing out soft feminine silhouettes. On the other hand, when looking for a structured look that emphasizes the A-line style's continuity, heavier fabrics like satin or peau de soie silk. These easily maintain shape. Organza and any other supporting fabric achieve the same effect. The other advantage they have is their ability to be layered in the creation of full skirts. The look of an A-Line wedding dress can also be affected by the embellishments chosen. Bead work or lace overlays lend formality to a simple dress while a dash of color via the use of bows and ribbons accords style to the ensemble.
For full figured women, an A-Line wedding dress lengthens a woman's entire body, taking focus away from the waistline. This type of dress also works well for petite women. Sheaths would not be a good idea as the have the effect of further shortening a small frame. Even the bottom heavy body type can enjoy the benefits of the A-Line wedding dress. Women with large bottoms and hips need a dress that will divert focus to their upper bodies. With the type of dress discussed, it is easier to do away with pleats and gathers at waist level. To accentuate further the desired figure, use corset style bodices with lace for detailing. If possible, show back, arms and bust line.
There are a number of things to consider. The A-Line wedding dress flatters almost every body type. The long lines of the princess dress discussed earlier slims down rounded figures and creates an illusion of agreeable height on shorter bodies. The A-line's fill skirt hides larger lower bodies, at the same time creating an illusion of shapely curves on narrow body frames. Due to the versatility of the A-Line wedding dress, simple, minor modifications to fabrics, waistlines, and necklines accentuate a woman's best features and hides those she wishes to hide. Even though aficionados claim the dress is best for women with smaller waists and brides with large thighs and broad hips, the facts have painted a different story.
