Cara Delevingne turns down 70 per cent of the work she's offered.
The model-of-the-moment is signed to Storm Model Management and co-founder Sarah Doukas has discussed what working with her is like.
Delevingne walked several shows during the recent Fashion Week season, has created a capsule collection for Mulberry and appears in many campaigns.
However, Doukas is determined not to let her become over saturated and explained many of the offers made to her are dismissed.
"We spend our lives saying no," she told students at Conde Nast College.
