"The market for menswear in China has been underestimated for a long time. It's not like men don't need to look smart or have the financial capability to spend, but it's in our traditional mindset that there is not a market for them. If there is any difference, it is that they are less willing to spend time on selecting styles and brands, which means higher brand loyalty," said Wei.

Consultancy firm Euromonitor International estimated that China's menswear market was worth over 572 billion yuan in 2018, up 7 percent year-on-year. While it still accounts for about one-third of the total apparel market, it is projected to enjoy a higher-than-average growth rate and surpass 612 billion yuan by 2023.

Everbright Securities estimated that China's tailoring market would be worth 200 billion yuan by 2020, almost twice that of 2016, and about 80 percent of the business would come from the mid-price sector.

In Beijing, a similar team has its eye on the market too.

Online business, Smart Shirt, which was launched in May, was introduced to China by four young Chinese people with similar academic background in aviation to the founders of Australian brand Decent Shirt.

After managing the Chinese factories for the Australian brand, the founders decided to bring the concept of C2M(custom to manufacture) to China, targeting those aged 20 to 30 in bigger cities.

In the first month following its launch on a WeChat mini program, it sold hundreds of shirts, which was better than expected as the small team spent nothing on advertising, according to Hu Shizhe, a 26-year-old co-founder of the company.

Looking ahead, Hu told China Daily that they want to become the country's best online tailor-made brand for men.

"Being the best does not necessarily mean being the largest, or the richest, but a model that is considered the prototype in the industry, which latecomers want to follow, and consumers aspire to," said Hu.

For Match U, the future plan is more concrete: to combine offline and online markets by working with conglomerates like Wanda and Suning.

The company has developed an AI body-measuring cabin, which consumers can walk into, turn around and have their measurements taken with the precision of a Savile Row tailor within minutes. The machines, which cost 100,000 yuan each, will be placed in cinema halls and shopping malls to help attract new customers for the business.
