Suits worn by former prime minister Margaret Thatcher before she took office are going under the hammer during an auction on Monday.
The seven suits are expected to fetch up to £1,500 each when they are sold at Christie's auctioneers in London.
Among those up for sale are a bright turquoise two piece she wore on the day she was elected leader of the Conservative Party in February 1975 as well as a striking yellow dress and jacket.
Other outfits include a gold and silver cocktail ensemble and a dark greatcoat with distinctive red lapel stitching.
"When you see the pieces in the flesh, the first thing that comes to mind is how powerful they are and how much they stand out," a Christie's spokeswoman said.
"It definitely shows that she was a woman in politics and she was making a name for herself and what she wore was a very important part of that."
Baroness Thatcher, 87, prime minister between 1979 and 1990 - was nicknamed the "Iron Lady" by a Soviet journalist for her uncompromising stance against foes both foreign and domestic.
Only a limited number of her personal items have ever been sold and her suits could fetch more than their estimated price after an exhibition showing the auction items has already produced a lot of interest, the spokeswoman added.
A black handbag Lady Thatcher was carrying in a picture with former US President Ronald Reagan sold for £25,000 in a charity auction last year.
