No. 3: Vidal Sassoon's Wedge Bob

Vidal Sassoon was a visionary London hair stylist who invented the ultra-popular geometric wedge bob in the 1960s. It's still considered edgy and chic today (Victoria Beckham's angled bob is a modern spin on it). While I may not be able to pull off this daring look myself, I still feel chic using his namesake product line.
