WHEN I was small, hours flew by with a few curlers, a stick of red lippy, green eye-shadow the consistency of emulsion and my Girl's World.

For those unfamiliar with the once must-have toy, this was a big doll's head with a mop of golden locks that 'grew' that you could make up to look like something which might smother you with a hairnet in the film adaptation of a Steven King novel.

But I would be happy for hours on end conjuring up glamorous hairstyles that resembled the kind of nest only a blind bird would build and took the next fortnight to brush out.

Now, various internet sites allow you to scan in a photograph of your own head, which you can then accessorise with any number of hair styles and glasses.

With a couple of clicks of the mouse you can see whether the image that looks so good on a size eight superstar really would suit you before shelling out at the hairdressers and risking having to wear a woolly hat for the next six months.

But you don't have to stop with the Jennifer Aniston or Meg Ryan hair-do.

Today, budget permitting, you could emulate a star's nose, jaw line and teeth.

An ever-increasing number of people are opting to change their appearance cosmetically and many visit their surgeon with a particular celebrity's features in mind, prompting experts to this week warn against expecting miracles.

In a survey of more than 250 cosmetic surgery patients, the most admired celebrity body part was model Kelly Brook's bottom.

Other sought-after features included actress Scarlett Johansson's lips, Keira Knightley's stomach, Kate Beckinsale's breasts, Charlize Theron's hips and Sienna Miller's nose.

The Harley Medical Group, which carried out the survey, also questioned men, who now make up 40 per cent of patients.

Actor Jude Law got the most votes for lips, while the most admired nose belonged to TV presenter Jamie Theakston.

Almost 75 per cent thought Brad Pitt had the best body shape, while David Beckham scored only eight per cent of the vote.

Director Louise Braham said: "While it is interesting to look at which celebrities are most admired for a variety of features, these are not benchmarks that a surgeon would use prior to surgery, despite the fact that patients may well mention certain celebrities' features during a consultation.

"We would never say 'Yes - we can give you Sienna's nose or Scarlett's lips'. Apart from anything else, what looks great on one person may be out of proportion or out of synch on another."
