Amir Khan will wear boxing's "most expensive shorts" when he takes on Devon Alexander in a boxing showdown in Las Vegas on Saturday.
The shorts, made of white nappa leather, silk and featuring a waistband made of 24-carat gold thread, are reported to be worth at least £20,000.
The Sheffield company Fight Label, who made the shorts, said Khan "wanted extravagant and we've delivered".
The winner of Saturday's bout could fight Floyd Mayweather next year.
The designer of the shorts, Sophie Whittam, told the BBC: "I think it's possibly the most expensive shorts ever made."
