One shop took up to 30 orders for the clothes in just half a day, according to the Beijing News, which also noted in its report Thursday that the garments' price had gone up by about 50 percent in 24 hours.
"This is definitely going to be a popular item as Big Xi wore it," one retailer told the newspaper, using a commonly used nickname for the barrel-chested Chinese leader.
