George Galloway is auctioning the tracksuit top he wore on Celebrity Big Brother on eBay.
Mr Galloway's top comes complete with sleeping mask and microphone
The Bethnal Green and Bow MP, who was criticised for imitating a cat on the Channel 4 show, is raising money for the Palestinian charity Interpal.
The top, bearing the word "Cuba", comes complete with Mr Galloway's microphone and sleeping mask.
Described on the website as "a piece of televisual history", bids for the item started at 99p.
With eight days and five hours to go, the price had reached £385.
Mr Galloway's spokesman told the BBC News website: "We are look for a five-figure sum. Previous Big Brother memorabilia has gone for thousands of pounds."
'Trendy and cool'
The Respect MP's overnight bag and suitcase are also for sale.
Mr Galloway - the "trendiest and coolest MP in town", according to the eBay advert - is offering to sign the items.
Mark 'bomber' Lancaster: the fastest MP on three legs?
He was criticised for taking time his parliamentary duties to appear on Celebrity Big Brother.
Mr Galloway, 51, was the fourth person to be evicted from the show, which was eventually won by "non-celebrity" Chantelle.
During his time in the Big Brother House, he pretended to be a cat "licking cream" from the hands of actress Rula Lenska, wore a red leotard, imitated Elvis and dressed as Count Dracula.
Mr Galloway donated his fee for the show to Interpal.
On Wednesday, he also took part in an MPs' three-legged race to raise money for the children's charities Childhood First and Whizz-Kidz.
A spokeswoman for Whizz-Kidz said Mr Galloway, aided by a fundraiser, had come second to a team including Conservative MP Mark Lancaster.
