You can never be too careful as Cara Delevingne proved when she trademarked 'Cara Delevingne' in a bid to stop other people latching onto her success. It prevents anybody from producing goods with her name on, from standard handbags and fragrances to umbrellas and even walking sticks, because that's just what everyone's grandmother has always wanted - a Delevingne-branded walking stick. She also bought the rights for Cara & Co. in the hope that she can one day set up a business selling her own fashion products including a range of onesies, although with her acting career poised to take off, it could be a while before Britain's streets are plastered with her designs.
