She shared the story at the 'Vogue' Forces of Fashion conference on Friday.
Wearing pieces from the collection — Karefa-Johnson in a lilac cashmere cardigan, Hadid, in an oversized blazer and sweater combo — the two real-life friends discussed the creative process in bringing the brand to life. Karefa-Johnson, who styles for Guest in Residence, commented on Hadid's intuitive taste in design.
The model revealed that as a small company of only 13, she's extremely hands-on, responsible for every detail, from color-combination to picking out buttons. She also talked about how "It was expected for me to come out with something that was a fast-fashion type situation... People use that to get to consumers quickly and make money quickly... but with this brand, I really want to support people and invest in pieces for a long time" she said.
