The fabulous life of legendary fashion billionaire Ralph Lauren, who dressed Melania Trump for the inauguration

Ralph Lauren has a long history of working with important American figures. The designer's most recent credits include dressing first lady Melania Trump for the 2017 inauguration.

Trump wore a powder blue Ralph Lauren suit, which many compared to the pale blue suit that Jackie Kennedy wore to her husband's inauguration in 1961. Ralph Lauren also designed the cream-colored suit that Hillary Clinton donned for the 2017 inauguration.

Ralph Lauren is a name synonymous with American fashion. His net worth is now estimated to be nearly $6 billion, according to Forbes. And yet, the story of how he built one of the largest fashion companies in the world from nothing isn't quite so well-known.

Here's how he amassed that wealth, and what he uses it for.
