Michelle Trachtenberg, aka the villainous Georgina Sparks on "Gossip Girl," has teamed up with bag designer extraordinaire Monica Botkier to create this chic bag (shown right, and featured on the Oct. 12 episode of the hit series).

"Working with Michelle has been a blast! She is quite talented and very dedicated to making this a success." says Botkier, whose bags and shoes are also loved by celebs including Angelina Jolie and Rihanna.

The blue leather "Michelle" satchel will retail for $545 and is available for pre-order now at botkier.com. It will also be sold on ShopBop in the next couple of weeks.

A portion of the proceeds from the bag's sales is going to Oxfam.org, a charity that helps fight worldwide poverty.
