Wedding Dresses come in a variety of different fabrics and designs, so it's a good idea to experiment and try different types to a sense of what suits you best get. Some wedding dresses have straps that can be plain or interlaced and look very attractive and others are strapless dresses and show off more of the shoulders. Off the shoulder wedding dress is a very flattering outfit with lots of corsets.
To draw attention away from your chest (if you are too conscious of the attention), is an off-shoulder gown recommended as it focuses attention upward to your shoulders. The effectiveness of different types of dress is very dependent on your physique and it's good to make sure you look as good as you feel, but if you feel uncomfortable, it is better to maybe see another design remember.
