Alongside with her husband Verbal, Yoon co-founded the notable jewelry label Ambush in 2004. The Tokyo’s fashion power couple excels at creating hip-hop and rock aesthetics with vivid colours. Yoon found her interest in fashion during her time in middle school and nurtured herself about style and look with fashion magazines over time. With an initial aim at custom-making jewelries for her husband Verbal, they have produced a number of lines of jewelry and have collaborated with brands such as A Bathing Ape, Topman and watch maker Georg Jenson. AMBUSH opened its first flagship store in 2016, a platform that displays the couple’s creativity and ideology.
