What you need for this look:
- A large, rounded brush (don't curl the ends too far under, lest you end up looking like an 80's throwback).
- A decent flat iron.
- 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.
