Gwyneth Paltrow's sophisticated long bob is a terribly sexy version of the bob. She parts the hair in the middle and the cut is at an angle -- a tad shorter in back than in front. Her naturally wavy hair is then flat-ironed to sleek perfection.
What you need for this look:
1. A large, rounded brush (don't curl the ends too far under, lest you end up looking like an 80's throwback).
2. A decent flat iron.
3. A gloss spray for after you iron. Bumble and Bumble discontinued their Gloss (why? why?), but their Shine spray gets high marks in the industry.
