Despite 28 years separating them, Ms Serene Soh considers her daughter Venus Yap, her style sister.
Ms Soh, 42, says she and her daughter shop monthly at haunts which "youngsters like", such as Bugis Junction, Cotton On, H&M, Forever 21 and Uniqlo.
"I am the one who dresses like her. It's pretty all right because the brands we buy are trendy, so there's no age limit," says the assistant retail manager (women's accessories) at Takashimaya department store.
Venus, 14, who shows the lookalike pictures of mummy and her on her mobile phone to close friends, says: "My friends are surprised my mum is so sporting and cool to wear the same clothes as me."
When Venus and her mother see an outfit they like, they buy two of it - mum gets the "more mature" shades (blacks, greys or blues), and daughter, the bright hues (pinks and greens).
Ms Soh says: "At times, if we want the dress in the same colour, we argue. But I'm the paymaster, so she gives in to me. And we take two of the same pieces."
Their dress-alike practice began when Venus was about 12 - mum used shopping jaunts as a way of spending time with her daughter.
Ms Soh is fine wearing cartoon character tops too. On a trip to Hong Kong Disneyland two years ago, she bought a Mickey Mouse T-shirt, that Venus liked, for herself as well.
"I don't feel childish. The cartoon character is older than I am," she says, laughing.
Ms Soh, who says she has not received funny looks from strangers, is undeterred by questioning from her 49-year-old husband, a deputy senior manager in a construction firm: "Why do you have to dress alike? Are you afraid people won't know you are mother and daughter?"
Nor does her 17-year-old son's typical comments - such as "Mum, you are not a teenager" - put her off.
If she had her way, she would be her daughter's dress double "for as long" as possible, says Ms Soh.
