The 'Navy Daisy and Rose' dress has been made exclusively for the V&A and is about as authentic as you can get without jumping in a time machine and going back 50 years to buy a similar outfit.
The dress has been adapted from a 1950s fabric designed for Horrockses Fashions, one of the most respected ready-to-wear labels of the late 1940s and 1950s. The shape of the dress was developed from an original 1950s day dress in the V&A's archives and it has a fitted waist and bodice.
Along with it's exclusivity comes a price tag of £95, but you're paying for a true recreation of beauty, in 100% cotton. But yours online.
