The dress was from the Victoria Beckham Spring/Summer 2013 collection and featured sexy lace panelling offset by a prim and proper pointed collar.

Rosamund added a pop of colour with a neon pink bra which complimented her nude and neon heels to perfection.

The actress opted for minimal hair and make up which added to her simple yet chic look.

This outfit is a quite a departure from Rosamund’s usual  conservative look and definitely showcases her more playful side.
