What is the full name of the male co-founder of Forever 21?

The full name of Forever 21’s male co-founder is Do Won Chang.

Do Won Chang founded the company with his wife, Jin Sook Chang, in Los Angeles in 1984. The couple had immigrated to the United States from South Korea and began the business with limited capital, opening a small clothing store in Highland Park. Their first-year sales reportedly reached about $700,000, helping finance rapid growth.

Chang and his wife initially operated the business under the name Fashion 21. They later renamed it Forever 21 and developed a fast-fashion model built around quickly changing styles and low prices. The company expanded through shopping malls and eventually became a major international retailer.

The name order can cause confusion because East Asian naming conventions may place the family name first. In English-language references, the founder is generally identified as Do Won Chang, while Chang is his surname. Jin Sook Chang was his co-founder and spouse, not an alternative version of his name.
