Best Dressed InStyle Forevermark Party January 2012

Ahead of tonight's People's Choice Awards, stars gathered at last night's Forevermark and InStyle bash in LA to kick-start a season's worth of award-worthy looks. Their style set the tone for the onslaught of what's to come, showcasing a chic mix of cocktail sheaths in leather, lace, and sexy sheer details. We spotted Jessica Alba in a sweet-cum-sexy play on ladylike dressing, Michelle Williams showing off her signature style in a pretty Versace frock, and Rebecca Romijn showcasing her stems in a flirty black mini.
