SEOUL (REUTERS) - In central Seoul's street fashion Mecca of Dongdaemun, more than 30,000 outlets and thousands of sewing workshops packed into a 2 sq km area churn out clothes in as little as a day.
That's a lightning pace compared to the one to three weeks needed by global "fast" brands such as Inditex's Zara and H&M.
Partly set up by displaced North Korean refugees after the 1950-53 Korean War, the shopping district was long home to seamstresses and merchants eking out a living by selling dyed military uniforms and, later, knock-offs of global luxury brands.
Now, Dongdaemun is emerging as a real power for Korea Inc, best known for its Samsung smartphones and engineering, leading its apparel industry's overseas expansion.
"Dongdaemun might be the only place on Earth where if a design is decided and ordered in the morning, raw materials can be purchased by noon at the latest and finished products start arriving at the shop on the same day," said Lim Joon-weon, director of operations at Lotte Asset Development's FitIn mall in Dongdaemun.
Behind the swift production is an ecosystem that includes 35,000 retail and wholesale clothing shops, the country's largest fabric market, and an estimated 5,000 sewing workshops of six to 10 workers each, operating in close proximity.
Similar turnaround time in an organically-formed fashion hub is unheard of even in places like Guangzhou in southern China, where the scale of the wholesale market is too vast to enable such rapid production, Lim said.
Privately owned E-Land Group Chairman Park Song-soo first opened a clothes shop in front of Seoul's Ewha Womans University in 1984, but is now in the forefront of the overseas expansion of Korean fashion brands.
E-Land began retail sales in China in 1997 and has carved out a slice of the fragmented fashion market as one of the top five apparel retailers, according to a 2012 Standard & Poor's report, with average annual growth of 60 per cent over the past 10 years.
It has more than 2,000 outlets in China and earned $1.8 billion last year, building its growth on different fits and colours for consumers in 60 different regions.
More recent fashion groups ride the coattails of the rising fortunes of K-Pop, Korean drama and celebrities like rapper Psy.
"Right now, the biggest draw is the 'Made in Korea' label," said Yun Bum-suk, founder of fast fashion brand JEIKEI and wholesaler that yearly sells more than 3.5 million pairs of jeans in South Korea, China, Thailand and Vietnam.
"Consumers in Southeast Asia tended to respond better to the exact colour and style they've seen in Korean dramas than to clothes modified to fit local tastes."
At Singapore's Wheelock Place in the shopping district surrounding Orchard Road, a new flagship store for the Headline Seoul brand opened in late April.
Its initial reception as a pop-up store in the Raffles Hotel last year was positive enough for founders to plan five more in Singapore and the Philippines and a shop in Malaysia to open later this year.
