One way to enhance your bust line is to add a sweetheart neckline. This will add a bit of flair to an ordinary bridesmaid dress or give you a special added touch to your wedding dress. Here is an illustration of how the process is achieved. The 1st picture is of an typical bridesmaid dress.
This next picture is of the bridesmaid dress turned inside out. You can see the stitching line of how a sweetheart dip is sewn in the center front of the neckline.
Next all of the extra fabric is cut away and the seam allowance is clipped.
And here we have the final results. As you can see this gives the neckline a special touch.
The bride that wore this dress chose it because her ceremony was on a cruise ship. She didn't want a typical white wedding gown and adding a sweetheart neckline made the dress her own.
