wants to show off her cleavage on her wedding day.
The singer-and-actress - who is engaged to former NFL player Eric Johnson - is currently deciding on what dress she will wear on her big day, but she already knows she wants a gown which accentuates her impressive breasts.
She said: "I like my collar bone. I have a long neck, so I like to show off my decolletage.
"I haven't really thought about the colour. But I do like the romantic feel of a lighter color."
Decolletage is a French word adopted by the English language most commonly used to refer to a neckline which reveals or emphasises cleavage.
The 30-year-old blonde is also determined to walk down the aisle in a dress which is different to the one she wore when she tied the knot with her first husband Nick Lachey
in October 2002.
Jessica - who divorced Nick in June 2006 - added to People: "It (the dress) is definitely going to be beautiful I want it to be different from what I've had before. I have a lot of tear sheets!"
The 'I Wanna Love You Forever' singer - who has her own fashion
label, the Jessica Simpson Collection, and designs her own lines of handbags
and shoes - has also come up with a unique choice for her bridesmaids' dresses.
She revealed: "I definitely would want all my bridesmaids to be in everything different. Just to reflect what their personalities are."
Jessica - who got engaged to Eric last November - hasn't set a date for her big day yet, but has confirmed the nuptials will take place before the end of the year.
She said: "My wedding, I still have no date but it will be by the end of the year."
