A nice alternative to the classic LBD, French Connection’s Cogs Dress has a lovely beaded neckline and a deep-V back that makes it much less demure than it may seem at first glance. We’re fans of the cinched-in waist, and think this is the kind of dress you’d end up wearing again and again, but without getting bored of it. It’s £140 from frenchconnection.co.uk.
