DO WON AND JIN SOOK CHANG, NET WORTH—$3 BILLION

We’re not sure if this couple qualifies as celebrities, but to some degree they must, because they found one of the largest apparel retailers in the world, Forever 21, which reportedly has around 470 different stores in 57 different countries. They first opened the chain in 1984 with a 900-square-foot store in Los Angeles and managed to hit $700,000 in revenue in the first year, prompting them to launch a new store every six months. Their revenue peaked in 2015 at an estimated value of $4.4 billion.

However, the couple filed for bankruptcy in 2019 because of a massive sales slowdown, but of course, they had already amassed a huge fortune by then. And there’s a lot to be inspired from the story of this couple because they immigrated to the US from South Korea with nothing but a high school diploma, and yet they were still able to create a billion-dollar empire with a not-so-good credit report and just a mere $11,000 in savings.
