YILEE is a London and Seoul based label founded by Lee, which is combining two ways of romanising her surname. Lee was born in Seoul, South Korea and moved to London to pursue her Bachelor of Arts in Menswear at the London College of Fashion in 2019, followed by a Master of Arts in Womenswear at the Royal College of Art in 2023.

Under the brand philosophy 'Shaping future-oriented yet timeless beauty', she addresses the tension between traditional craftsmanship and avant-garde elements equally within the same piece. Witnessing a future where fluidity and volatility are accelerating, she has contemplated how unalterable and sustainable values can be defined not only as a designer but more as a creator. This manifests through unorthodox pattern cuttings, solid garment construction with high-quality materials and disruptive silhouettes. She believes that those elements can bring forth their own unique aesthetics and impressions, not being consumed rapidly by observers or wearers but rather giving a timeless beauty that can be present eternally.
