Nicole Richie is finally ready to walk down the aisle ... and we're all ready to see what dress the reality star-turned-designer chooses for her special day.

It appears the winner is Marchesa.

E! Online reports that Richie will be wearing a creation from Georgina Chapman and Keren Craig's label when she weds rocker Joel Madden at father Lionel Richie's Beverly Hills estate tomorrow. According to the website, she and stylist Simone Harouche were in New York for a fitting last week and it "went very well."

Stylist April Steiner, who has dressed Nicole in the past, has her own predictions about what Richie's dress will be like. "I would not put her in pure white ... I would go more off-white or even a very pale pink, soft and elegant is what I envision. I would like to see her in a strapless gown or a one-shoulder. She is so tiny, so the more skin, the better," she tells RadarOnline.

Richie is known for her boho-glam style but was spotted on the red carpet in an elaborate tulle Marchesa confection at the opening gala for the Resnick Pavilion at the LACMA in LA. Get More From StyleList
