Champion boxer Amir Khan is to donate his Sheffield-made shorts - estimated to be worth £30,000 - to help rebuild the Peshawar army school where 141 children and staff were killed by the Taliban.
The Briton, who is of Pakistani origin, wore the shorts in his win last weekend against Devon Alexander.
The shorts, made of white nappa leather, silk and featuring a waistband made of 24-carat gold thread, were created by Sheffield firm Fight Label.
“It was just very sad to see innocent kids being killed,” said Khan, 28.
“I want to donate the shorts for the Peshawar cause, rebuild a school and strengthen security around the area.”
Khan, who defended his WBC Silver welterweight title in Las Vegas, became a father in May when his daughter Lamysa was born.
“We are very lucky in England. We have good security and I will be able to send my little girl to school and know she will be fine, but in Pakistan you cannot do that.
“They send the kids outside the house and do not know if they are going to come back. It’s very sad to know that,” he added.
Sophie Whittam, who designed the shorts, said Khan said he ‘wanted extravagant and we delivered’.
“I think they are possibly the most expensive shorts ever made,” said Sophie.
She said the garment had taken four to six weeks to complete, working on different designs and colours.
