BICESTER, England - The designer outlet mall of Bicester Village is set in the English countryside near Oxford, but it might as well be in China.

Quiet Mandarin chatter fills the air. Most of the shoppers are Chinese - and so are half the sales assistants.

In the Burberry store, many try on the brand's signature trench coats, which go for at least 600 pounds ($925) after discounts. Some punch numbers into their smart phone calculators to work out the exchange rate; more take photos of the goods on offer, likely to message friends at home for a nod of approval.

"I don't know too much about designer labels. My friends tell me what to get," said Andy Cao, clutching about six shopping bags. He came from Shanghai to Europe with a group of about 30 colleagues to shop and do some sight-seeing.

Over the past decade, Chinese customers - at home but most crucially abroad - have become a powerful market force in the global trade in expensive clothes, jewelry, watches, perfumes, drinks and handbags.

But the stock market plunges of the past few days on the Shanghai exchange have raised the question: Will the drop in the Chinese economy be worse than expected? And how will it affect the Chinese shopper?

John Guy, a luxury goods analyst at financial services group MainFirst in London, said there has been some shift in demand away from the very high end of prestige brands, for example for watches. A government anti-corruption campaign has played a role by leading many people to avoid conspicuous consumption.

"The crackdown on gift-giving means you're no longer buying gifts, you're purchasing for your own consumption, and that has led to a shift in terms of the selling prices being effectively lower," he said.

But other data, such as increasing outbound travel, suggest "the traveling Chinese consumer is still there."

He noted that the income of the middle class in China is forecast to grow faster than the economy. Chinese authorities are trying to shift the economy's focus on manufacturing and exports toward consumer spending - something that could sustain shoppers' ability to buy Western goods over the longer term.

And while the Chinese economy is slowing, it is doing so from a high level. It was growing seven percent annually at last count, much faster than Western countries.

Gerald Celente, a business consultant who publishes the Trends Journal, takes a gloomier view of China's economic downturn.

"It's going to have the same kind of effect that it has in any nation - retail slows down," said Celente. "You're seeing the people that made it big quick, lose it fast."

Already before the stock market turmoil, demand for luxury goods was waning in China. The Bain & Co. consultancy predicted this spring that China's luxury sales would drop 4 percent this year.

Currency differences, combined with high taxes and markups for imported luxury goods at home, mean that Chinese shoppers are confident they are getting goods for some 30 percent cheaper in continental Europe.

The Chinese government has recently cut import tariffs, and producers have lowered prices in some cases, to encourage more spending inside China. But many of the shoppers here say they'd still rather come to Europe.

"It's still cheaper here than back home, even after the government measures to reduce prices," said Cao, who works in logistics.

Chinese spending in Britain is not growing as quickly as it used to, but the Chinese are still the top overseas spenders in the country, according to Global Blue, a Switzerland-based tax refund company that works in over 40 countries. In 2013, Chinese spending in Britain grew a whopping 34 percent compared with the previous year. In 2014, that slowed to a 6 percent growth rate. The company estimates that the Chinese shopper spends 778 pounds ($1,200) per transaction in Britain.

Hong Kong businessman Verdi Cheng, shopping with his family in Bicester, is upbeat despite the stock market turmoil. He's taking some time out with his daughter, who is just about to start at an English boarding school.

"The recent market volatility has burnt me pretty badly," Cheng said. "But it's the nature of markets to go up and down. It's just part of the cycle and it's bound to bounce back. I think the worries are hyped up."

In mainland Europe, a weak euro has served as an added attraction for international shoppers, including the Chinese. LVMH Chief Financial Officer Jean-Jacques Guiony said that "most of our brands are benefiting from a strong momentum from the Chinese client base. It's particularly true for Fendi and Celine." Louis Vuitton has seen stronger demand as well.

In Paris, Amanda Wang, a 34-year-old tourist from Hong Kong, says the stock market crash hasn't affected her and argues that it's probably too early to affect most people.

"It's not going to stop people buying clothes," she says outside Dior's Avenue Montaigne store. "The Chinese love French fashion like Louis Vuitton, Chanel and Dior."
