Amir Khan will wear boxing's "most expensive shorts" when he takes on Devon Alexander in a welterweight 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 £30,000.
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 BBC Radio 5 live: "I think it's possibly the most expensive shorts ever made.
"We worked closely with Amir's team. For around four to six weeks we've been working on designs and colours and obviously Amir and his family had a little bit of input, but at the end of the day it's what we think is going to look best. It is a very involved process."
Khan, 28, has already donned a pair of eye-catching shorts in the build-up to the bout with Alexander, who has won 26 of his 28 career fights.
The Bolton fighter sported a pair of black shorts made of "Versace material" and featuring more than "1,000 Swarovski stones" for a media workout on Wednesday.
Khan is preparing for his first fight since defeating veteran American Luis Collazo on his welterweight debut in May.
