Mainly inspired by 60's and 70's, you will find her in many flowy Bohemian looks (loves her caftans) and Disco era sequin tunics and dresses. You'll rarely find her wearing flats; I was impressed with how she rocked stiletto, platform, thigh-high boots while 9 months pregnant. She mixes different textures into her look and is amazing at layering and accessorizing. There is a lot of bad press about her being too thin, but she definitely seems like a work-a-holic, who probably barely makes time to eat. Either way, she knows how to dress for her body and looks great.
Last year Rachel launched her own high-end line (she already has another through QVC). Although I know she isn't a proper designer, I'm loving what she is putting out, probably based on her archives, taste and knowledge of fashion.
Here are just some of my favourite looks she's worn:
