Even in childhood, he designed and created clothing to dress dolls and, in 1965, he became an apprentice of the tailor Cheickene Camara at Kati.
He soon moved to Abidjan (1969) and then to Paris (1971), where he worked first for Yves Saint-Laurent and then at Mic Mac with the stylist Tan Guidicelli.
For the new line, Seydou designed Western-style jackets and miniskirts from traditional African patterns and fabrics, marketing the clothes in the United States, Europe, and urban West Africa.
In 1993, he founded the African Foundation of Fashion Designers, but died in 1994 with 44 years in Bamako of AIDS.
Atelier Chris Seydou, a group of tailors who worked with him in the past, continue to produce a bògòlanfini clothing line in Bamako.
