Lancôme is bringing back its genius Pout-à-Porter series for spring 2010!

The collection -- for which the makeup giant brilliantly teams up with fashion designers to create limited edition lipsticks -- first debuts on the runway, then promptly sells out at cosmetic counters.

Past collaborations include Thakoon, Peter Som, Benhaz Sarafpour and Proenza Schouler. (You may remember a tube of "Proenza Pink" selling on eBay for $122.50!).

For spring 2010, Chris Benz is the designer of choice, and he announced on Facebook a fun contest to name his color.

Simply go to Benz's page and post your name suggestion based on what you know about his designs (hint: rebellious preppy).

The winner will get five of the lipsticks and a $500 Lancôme gift certificate. Score!

You have until 5pm EST on July 12 to enter, so get creative asap and good luck!
