The designer is Ralph Lauren's nephew, and is a versatile person who not only designs clothes, but also works as an actor and artist.
The brand GREG LAUREN is known for its products that are made by collecting and upcycling fabrics.
The fabric used for this jacket would likely have been used to make a well-tailored suit.
He has infused it with a design that resembles a gilet, elevating it into a new piece of clothing.
One of the things I like about GREG LAUREN clothes is that they can be designed to suit the original.
