For summer 2009, the young Hollywood starlet set has been embracing a groovy hippie look.

From long flowing patterned dresses, to flowers in their hair, to teeny short shorts, this style is definitely in.

Summer's hottest hippies include Lauren Conrad, Nicole Richie, Mischa Barton, Vanessa Hudgens, Miley Cyrus, Halle Berry, Joss Stone, Lindsay Lohan, and Mary-Kate Olsen.

Implications - Sneaky businesses that want their fashion trends to become all the rage will use celebrities to make their products popular. Sometimes a celebrity will be a fan of a product without the business knowing and will help to generate heaps of income for that company. Since so many people look up to celebs, it is good to have them on your business' good side.
