Just in time to kick off the 2012 fall fashion season, Yoplait^® is teaming up with Marie Claire to challenge consumers to tap into their “inner fashion designers” via an interactive Twitter contest. The #SOGoodfashion challenge asks consumers to transform their Yoplait look from “good” to “SO good!”

For a chance to win an ultimate fashion experience courtesy of Marie Claire, consumers can follow @Yoplait on Twitter and tweet the brand a self-portrait of an original fashion look inspired by one of Yoplait’s 40 flavor names, along with #SOgoodfashion. The contest runs now through September 1 at 11:59 p.m. EST.  Limit one entry per person.

“Marie Claire has millions of fashionable followers and as a leading voice in the industry, we’re excited to partner with them to put our stylish consumers in the front row of fashion,” said Elizabeth Green of Yoplait. “We love to see what makes our followers feel ‘SO good’ and we can’t wait to surprise one of them with a truly remarkable fashion experience.”

The grand prize winner, selected by Marie Claire, will receive an exciting prize package that includes:

• An all-expense paid trip to New York City to tour Marie Claire’s offices, visit the coveted fashion closet and meet fashion director Nina Garcia
• A photo shoot at Marie Claire for a custom Yoplait advertorial to be revealed in the November 2012 issue of the magazine
• Free ticket to attend one New York Fashion Week show with Marie Claire in September 2012

Plus, one runner-up will receive a new Marie Claire-styled wardrobe.

All entries will be judged by the Marie Claire fashion team based on the following criteria: creativity (25%); style (25%); originality (25%); and fashion (25%). In the event of a tie, the person among the tied entrants with the highest score in style will be the potential winner. The winning photo will be revealed on Twitter via @Yoplait with a congratulatory tweet from @marieclaire.
