The original Lara Croft outfit is up for grabs in a global online auction in aid of Unicef, conducted by web auctioneers eBay.
The outfit has been donated to the charity by Eidos Interactive and will appear on sale from 26 April for a period of 10 days. The money raised through the auction will go to Unicef's United Nations Children's Fund, to enable children across the world to have proper schooling.
The costume, which will be auctioned along with a certificate of authenticity, features Lara's trademark green rubber all-in-one vest and military-style shorts and is accompanied by the character's twin Smith and Wesson automatic replica pistols complete with leather holsters.
Nell McAndrew modelled the famous outfit from 1998 to 1999. It is expected to become even more collectable, as Lara will never be seen wearing this style of outfit again in games (a new outfit was unveiled last month by the new Lara model Jill de Long). This will give the old outfit classic status, which should drive the bidding and push up the final donation to the charity.
Rose Nelson, regional fundraising manager of Unicef UK, said: "Education opens an infinite number of doors for children and it is our hope that all children everywhere can receive their right to a basic education.
"We are extremely grateful to Eidos and the public for supporting our efforts."
