Mothers may pass their genes down to their daughters, but it appears the reverse is true when it comes to their taste in jeans.
Among females, at least, the mimicking of fashion styles passes up the generations, according to research in the United States which has identified a "consumer doppelganger effect".
Teenage girls were found to exert a strong influence on their mums' choice of makeup and clothes, not just for individual items they bought but in the overall "look" they wanted to present.
The survey of 343 pairs of mothers and daughters, with average ages of 44 and 16, showed that mums with a high fashion consciousness will deliberately adopt the looks of their daughters if they believe them to be stylish.
Perhaps unsurprisingly, even teenagers who are mature for their age show little interest in taking fashion tips from their mothers.
