Every bride should know something about wedding dress silhouettes before purchasing her dress. A silhouette should work well with your body type, personal style, and wedding, among which the most important one should be body type. You obviously want something flattering. Next, you want something that works with your personal style. This would be the type of dress you dream about or see in magazines and say “I want that.” Lastly, make sure it works with your wedding. If you have a small private wedding on a beach, it’s unsuitable to have a silk princess ball gown. Below are some guidelines: 
A-line
Best Body Type- This works well with almost all body types. The A-line makes round bodies appear slimmer and short bodies appear taller. The lines of the skirt hide the lower body of those with hips and can add the illusion of curves to those with less shape.
Personal Style- traditional, elegant, refined, girlie
Wedding Setting- The A-line is perfect for traditional weddings! Whatever your religion, an A shaped flare is surely the best. It’s not too over the top and not too casual. Therefore, it works perfect for a medium sized wedding.
Ball Gown
Best Body Type- Great for brides who are a little bustier. This shape draws the attention down and balances the proportions. Perfect for the inverted triangle body type.
Personal Style- over the top, girlie, bold, romantic
Wedding Setting- This silhouette works best for over the cheap weddings. Usually over 200 guests, in a large ball room, with large floral arrangements. 
Princess Length
