In 2011, Nonoo launched her own fashion label. While working for a tailoring company in Manhattan, she designed and made women's jackets in her free time after work. Nonoo was spotted at
Prune restaurant by a senior buyer from
Intermix, a chain of designer fashion boutiques, wearing one of her own designs, and received a purchase order of $150,000 for her first collection. She was named to Forbes' 30 Under 30 in Art & Style list as well as Crain's New York Business’ 40 under 40 in 2015. In 2015, Nonoo received media attention for producing an "insta-show" via
Instagram. She was the first designer to produce a fashion show exclusively on Instagram for her spring collection during
New York Fashion Week. By September 2017, Nonoo had released seasonal collections and begun manufacturing all products on-demand, claiming this reducing waste and lowered costs for her customers. In 2019, Nonoo collaborated with
Meghan, Duchess of Sussex on a clothing collection for the women's charity group Smart Works, along with retailers
John Lewis,
Jigsaw and
Marks and Spencer. == Personal life ==
