The uniforms will be displayed in a Design Museum exhibition
Three new design ideas for Beefeater uniforms have been unveiled at the Tower of London.
A female Beefeater costume, a helmet shaped like a lion's head and a winged tunic were devised as alternatives to the traditional scarlet uniform.
They are among a number of ideas designed to improve the city on show at south-east London's Design Museum.
Other inventions in the Super Contemporary exhibition include new versions of bus stops and phone boxes.
There are no plans for the Beefeaters to wear the new costumes, to be displayed as part of the exhibition, which opens on Wednesday.
They will feature alongside fashion designer Paul Smith's 5ft (1.5m) rubbish bin in the shape of rabbit, which has ears that flash when rubbish is placed inside it.
The Tower of London's Yeoman Warders date back to 1485 and their nickname Beefeaters is thought to derive from the daily ration of meat they received.
In 2007, Moira Cameron became the Tower's first female Beefeater.
