Mariah Carey, the only lady more girlie than an actual Barbie Doll, had a whole design competition for a dress to match her new fragrance, Luscious Pink!

The winning designer, 20-year-old Julian Contreras from San Jose, Calif., created one of the most fabulously, outrageously pink gowns we've ever seen. The pink couture masterpiece was brought to life by Mariah's personal stylist, and the singer recently wore it out to a romantic dinner with her husband, Nick Cannon (right).

Only three Luscious Pink dresses have been created -- one for Mariah, one for the winning designer (not that he's going to wear it) and the third is being auctioned off on eBay to benefit Susan G. Komen for the Cure. That means you can bid today through May 30th to win Mimi's Luscious Pink dress and support one of her favorite causes!

Check out the gorgeous design -- nice work, Julian!
