Designer Mooyeol Lee was born and raised in Seoul, the South Korean capital.

He graduated from SADI (Samsung Art and Design Institute) in 2010 as a scholarship student, and later worked in the design team of local menswear brand m-vio, soon channelling a desire to create under his own name.

In 2011, Mooyeol left the company and set up his brand YOUSER, showing his collections on the runway during Seoul Fashion Week from 2015. YOUSER is based out of a showroom in Korea, although has achieved steady growth within Asian and European markets over the past six years.
