* Americas biggest market as growth rate slows in China

MILAN, Oct 28 (Reuters) - Luxury goods sales this year are expected to outpace 2012 in real terms with the Americas overtaking China as the leading growth engine, Bain & Co said in a study on Monday.

The consultancy, whose forecasts are closely followed by the industry, said worldwide sales of personal luxury goods would rise 6 percent at constant exchange rates in 2013, higher than the 4-5 percent it had forecast in May and the 5 percent rise seen in 2012.

The growth rate would be only 2 percent at current exchange rates, mainly due to the impact of the devaluation of the Japanese yen.

The worldwide market in luxury clothing, watches, perfumes, cosmetics, jewellery, and accessories such as belts, ties and shoes, is set to be worth 217 billion euros ($299.33 billion) in 2013, Bain said.
