Marks and Spencer launches 'Best of British range' with suits it claims 'would cost £2,000 in Savile row' It has provided generations of young men with the suit for their first job interview - and change from £100. And while Marks and Spencer has steadily increased the quality and price of its formalwear, school leavers on a budget can still buy a suit for as little as £69. Now, however, the high street retailer has decided to take a dramatically different approach, by launching its most expensive suit yet. As part of the promise, the new suits have been designed in Britain, will be made in Britain and use British wool There will be four designs, and only 150 of each will be produced and sold in just five stores It will be made in tiny quantities at long-established British suit makers. When the "Best of British" range goes on sale in October, it will include suits for £799 - £300 more than its current most expensive ones. The store's head of design, Tony O'Connor, claims it will be a chance to buy "a suit that would normally cost £2,000 off the peg in Savile Row for £800." M&S made a three-year promise in February to launch a range of clothes to champion this country. The new suits have been designed in Britain, will be made in Britain and use British wool. The company, which has faced criticism for chaotic layout and a lack of sales staff, is under pressure to win back customers - and hopes their exclusive range will draw in shoppers The wool is made by two companies in Yorkshire: Abraham Moon, founded in 1837, and Alfred Brown, founded in 1915. The suits themselves are being produced at a factory in Cheshire, which can make just 30 a week. There will be four designs, and only 150 of each will be produced. They will be sold in five of M&S's British shops - Marble Arch and Kensington in London, Edinburgh, Bluewater in Kent, and Camberley in Surrey. The suits will also be sold online and in its shops in Paris and Shanghai. The company, which has faced criticism for chaotic layout and a lack of sales staff, is under pressure to win back customers.
