The stunning gown – which was created by Sarah Burton for Alexander McQueen for Catherine’s nuptials last April – is in the running for the prize along with the London 2012 Olympic torch.

They both feature in the Design Museum’s annual awards alongside the Olympic velodrome in east London and the comedy carpet in Blackpool – an engraving at the foot of Blackpool Tower featuring jokes and catchphrases of more than 1,000 comedians.

The longlisted designs are in seven different categories including architecture, fashion, furniture and transport.

They will go on show at an exhibition at the museum, in Shad Thames, south London, from 8 February, although Catherine’s dress – which was displayed at Buckingham Palace last summer – will not be included.

The overall winner for Design of the Year will be announced at a ceremony at the museum on 24 April.

Exhibition curator Ria Hawthorn said: “From the everyday practicality of a carefully crafted dining chair to the thought-provoking solar powered 3D printing machine that points to the future, this year’s nominees reflect the diversity of design in all its forms, showcasing designs that will have an impact on our everyday and future lives.”
