A leather crop top with power shoulders and two pockets on the chest - not exactly the easiest item of clothing to pull off. So - trust British beauty Rosie Huntington-Whiteley to go and look amazing wearing exactly that at Balmain's LA dinner party on Thursday night.
The supermodel paired the crop top with a monochrome mini skirt and mesh ankle boots - all very on trend and perfect for partying. As for Rosie's fellow guests? Liberty Ross lit up the room in an electric blue dress while Nicole Richie was pretty in pastels.
Yep, these girls have got their party style sorted. We wouldn't expect anything less.
