The former Chanel model said she has been thinking of getting into fashion design for years and had finally decided to start with the kinds of clothes she wore all the time as a working mom such as cashmere dresses and sweaters.
"Effortless chic. That is the idea of it," she added.
Schiffer's collection included long tube black and navy blue dresses, gray over-sized cardigans and cable-knit sweaters costing from 250 to 500 euros ($360-$725).
The sweaters had been bought by about 50 stores worldwide and would also be on sale next week at online retailer net-a-porter.
