The Wrap Dress
I think it is common knowledge that the Wrap Dress is one of the most flattering dresses you can put on your body. No matter your shape or weight, a wrap dress can give you curves and amazing cleavage.
These dresses have been popular since the 60's & 70's with Diane Von Furstenberg's name being at the forefront of the wrap dress movement. She is actually still selling amazing wrap dresses which can often be seen worn on the Wendy William's show.
I found this dress at New York & Company, and although it isn't a Furstenberg it is still gorgeous and most importantly affordable.
