Nicole Richie at the launch party for her maternity line designed for A pea in the pod, on August 6.
Nicole's little black dress is actually a sleeveless scoop neck tank top from her maternity collection designed for A pea in the pod.
"This is a tank from my line but I got it in a bigger size so I can wear it as a dress," Nicole told People magazine of her black tank.
The stylish mommy accessorized her outfit with a gold medallion locket necklace and a leather sunburst ring. Both are from her House of Harlow 1960 jewelry collection.
You can buy Nicole's top/dress in black or ivory from apeainthepod.com for $48.
