Two teenage girls took the concept of getting all dolled up for the school prom to an extreme - dressing as life-size Barbie dolls and being wheeled in still sealed in their boxes. Sammy Burns and Megan Barton, both 16, wanted to arrive in something more original than a stretch limo or black cab. It took a fortnight to make the 6ft-high boxes out of cardboard, wallpaper and pink paint - complete with barcodes, price tags and the logo of Barbie manufacturer Mattel.
