The key is to know your body type when buying your wedding dress, there so many kinds of wedding gowns you would find at physical store, and fall in love with them. If you are looking for wedding dress for your big day, you must know about these classic sillhouettes.

A-Line: Fitted bodice through the waist and flows out to the ground, resembling the outline of an uppercase "A." Ideal for all body types.
Modified A-Line: Fitted on the bodice and hips and gradually flares to the hem, forming an “A” shape. The skirt of a modified A-line wedding dress fits closer to the body than a traditional A-line. Ideal for all body types.
Ballgown: The “fairy tale” dress, with a fitted bodice, flairs at the waist with a full skirt. Ideal for most body types but looks great on pears, since it hides the lower body. Not good for petites; the skirt can be overwhelming on a small frame.
Trumpet: Fitted through the body and flairs mid-thigh. The cut is between a modified a-line and a mermaid cut. Ideal for frames with small waists, such as the hourglass, banana, and petites. Not good for pears and apples, as it accentuates stomach and hip area.
Mermaid: Fitted on the body from the chest to the knee, then flares out close to the knee. Ideal for slender frames and hourglass body types who are willing to show off their curves. Not good for apples and plus size body types.
Sheath: Narrow shape that flows straight down from the neckline to the hem. Ideal for lean frames, such as petites and bananas. Also good on hourglasses who are willing to show off their curves. Not good for pears; sheaths will accentuate extra inches and can be unflattering.
