The term ‘One Size’ refers to a size that is commonly specified by wholesale brands in Dongdaemun as being midway between sizes S and M for Korean women. This approach is adopted due to the perceived risk associated with producing a wide range of sizes. In the Asian retail market, including Korean and other Asian retailers, ‘One Size’ is usually purchased as a sample to gauge market reaction. Most Asian clients do not typically place custom orders, as the bulk order of ‘One Size’ is deemed suitable for the physical conditions prevalent in the region. However, clients in Europe, the Americas, and the Middle East tend to procure ‘One Size’ as a sample and subsequently place custom orders for different sizes.
