The so-called elephant pants are rarely worn by local Thais, but these light and breezy trousers can be found in abundance in tourist areas such as along the pubs and hostels of Bangkok's Khaosan road, once made famous by the 2000 film The Beach starring Leonardo DiCaprio.
There, they're a phenomenon worn by a near majority of tourists during the day, when they are sold on the sides of the street for as little as 150 baht each (US$4.90) each.
Shopkeeper Sawat Daengurai said he has been selling clothes on Khaosan road for about a decade, however. Sales only started picking up when he began to sell the elephant pants around three years ago, the German News Agency, dpa, reported.
Marissa Arranz, 50, from Spain said she has been to Thailand three times and has never failed to buy a pair on each visit. "They're really comfortable to wear. They feel so fresh," she said.
The wild patterns on the trousers resemble the designs of stitches that can be found in apparel made by hill tribe villagers. But the elephants that intersect the patterns mark the trousers with a distinguished Thai identity.
Elephants are the official national animal for Thailand and are deeply rooted in its culture and literature. The animal once featured prominently on the national flag.
"Foreigners like the pants because when they see the elephants they think of Thailand," says Mantana Kernkangpu, a 44-year old merchant of elephant pants at MBK shopping Centre in Bangkok, another major tourist destination for its cheap products.
Although the trousers may look Thai, Mantana said: "I wouldn't wear them myself. I'm too old. They're not my style."
Cultural scientist Adam Geczy from the University of Sydney said the elephant pants have a clear resemblance to harem pants from the early 20th century.
