Stepping out for a good cause, Nicole Richie was looking lovely at March of Dimes’ Celebration of Babies at the Four Seasons Hotel in Beverly Hills on Saturday (November 7).

Not far removed from giving birth to her second child, the former “Simple Life” star attended the annual event celebrating celebrity mothers as role models – all while raising money for their effort of ensuring healthiness to as many babies as possible.

Meanwhile, Miss Richie is also readying for the release of her second retail endeavor, a new line called Winter Kate which features “Nicole’s signature maxi dresses, delicate chiffon and lace jackets and tunic tops featuring ethnic-style prints.”

Of the offerings, Nicole tells, “Fashion should be accessible. That was my philosophy when designing House of Harlow 1960 and it remains my philosophy for Winter Kate. I started working on this collection in early 2009, the pieces can be dressed up, made casual but most importantly, they provide the wearer a means of self-expression and fun.”
