Miley Cyrus and Avril Lavigne were both spotted out and about this week in floor-skimming black maxi-dresses.
We love this navy blue maxi jersey dress with rope halter neck strap from Topshop, £100.
Definitely not a throwaway one-season number - it's such a classic you'll be able to wear year after year.
Go casual like Miley by teaming your maxi with cute flip-flops or grunge it up Avril-style with a trucker cap and shades.
