Ronny Tong Ka-wah wears a second-hand wig in court that he bought four decades ago in Britain for a mere £8.
And he has not cleaned the delicate piece since buying it, fearing it may not survive the stress of washing.
The lawmaker, who is also a senior counsel, recalled how he came to possess the wig.
"The original owner was a law student who bought it with an expectation that he would pass the exam to become a barrister. But he failed," Tong said. "So he posted the wig up for sale at Oxford University and sold it at half price, which was £8."
A handmade horsehair wig produced in Britain costs about HK$4,980 in today's Hong Kong.
Tong said he had never washed or dry-cleaned the wig before, for fear that it would fall apart. "It is made of horsehair that is glued together and is not very strong."
