Kiko Kostadinov (Bulgarian born 1989) is a Bulgarian fashion designer based in London. He currently is the creative director of his eponymous label as well as British heritage brand Mackintosh’s premium line Mackintosh 0001. Kostadinov’s work is centered on modern-day uniform and contemporary workwear.

Emigrated to London at the age of 16. His father was a construction worker, while his mother was a childcare worker and cleaning lady. During his upbringing in Bulgaria, Kostadinov’s only exposure to arts and culture was receiving clothes from his uncle who resided in London. Although he was interested in his own personal style, Kostadinov was never exposed to fashion in Bulgaria. Kostadinov’s clothing is greatly influenced by fellow designer Yohji Yamamoto. He is also inspired by designers Rick Owens and Christopher Kane.
