If you’re opting for just one bridesmaid, I love the idea of choosing a stunning designer gown for your number one girl in favour of the usual bridesmaid designs. This gorgeous silk gown from Calvin Klein is a great choice to create an elegant and sophisticated look for summer.

Especially perfect if your friend is lucky enough to be tall and statuesque, this floorlength halter neck isn’t as inaccessible as it looks. With long swathes of jersey silk, it skims the curves to create a wonderfully flattering silhouette, and heels can always add those extra inches we all covet in height! Best of all, its elegance lies in the simplicity, with simple lines and no embellishment for added class. Get this dress from Net-a-Porter for £1090.
