In the past week both these Rachels — Rachel Bilson and Rachel McAdams — have demonstrated notable style. Rachel Bilson is about to star in a new TV series and, styled by Nicole Chavez, has been trotting out the cuter end of the Chanel couture collections for her upfront events. As a team, Rachel and Nicole have an uncanny ability to pick the items out that will really suit a petite, yet curvy, figure. There is almost never a foot wrong and this stylist-actor pairing is one of the most successful in Hollywood.

Rachel McAdams is, of course, the female lead in the new Woody Allen movie, and as such her profile is definitely on the up. I love how she has combined her soft, blonde curls and waves with modern retro styling in these two looks. With hints of 40s and 60s in here, she is hard to define, and yet unquestionably a movie star. I think this style really works for her. The dress is magnificent and by Louis Vuitton and the jumpsuit is Azzaro.
