Mothers in particular favour New Sindy
There can hardly be a woman in Britain who doesn't declare herself a Sindy Girl or a Barbie girl.
For decades both dolls fought a battle for dominance of the market, which at times even reached the law courts.
Four years ago, the company that owns Sindy began planning a new future for her.
And this weekend, after a £3m make-over, Sindy is back.
And her new look is inspired directly by her original incarnation in the early 1960's.
Back then her style was pretty, but wholesome.

However, she quickly faced competition from the much more mature-looking Barbie.
Her then owners, Hasbro, decided to make her older, leggier and bustier, to try and compete with Barbie, and to try to get in to the American market.
Hence "Rainbow Sindy" was born.
But even she couldn't stem a sales decline.
So the new Sindy is much younger, and less curvaceous, than Barbie.
"It's a body that's sporty and pretty," says her chief designer, Barbara Calderwood.
"But it's not the body of an older woman."
New Sindy also drives a pink New Mini, a statement about her Britishness, which contrasts directly with her American cousin, who naturally drives a Californian beach buggy.

Mothers in particular seem to appreciate Sindy's new modest look.
Many believe she's more age-appropriate, particularly for three- to five-year-olds.
"This is what I'd want my child to be like, rather than this leggy tarty-looking person that Barbie has become over the years," says Jane Mason, a mother of two.
Sindy's relaunch is a big gamble for the Devon-based firm Pedigree Toys.
Having originally licensed Sindy to the toy giant Hasbro, the company bought back the rights to her five years ago.
Hence her return to modesty.
But whereas Sindy once only had Barbie as a rival, there are now many others, including the market-leader, Bratz.
If purchasing decisions remain with mothers, Sindy could be about to have the last laugh over Barbie.
Of course their little girls may decide otherwise.
