Stella McCartney hardly requires an introduction. Since she launched her London-based brand 15 years ago she’s been one of London’s most respected designers; we look to her for excellently tailored dresses and blazers that have just the right amount of personality. Stella’s also a life-long vegetarian, and never uses any leather or fur in her designs; her gorgeous faux fur and faux leather have made her a global leader in cruelty-free clothing.
