They've transitioned from young, small screen stars to fashion gurus, and the Olsen twins were busy tending to a clothing event at Pier 57 in New York City on Wednesday afternoon (January 25).

Mary Kate amd Ashley both looked darling as they joined JCPenney President Michael Francis, as well as Charlotte Ronson and Nicole Miller, for the Big Apple based JCPenney launch function.

The Olsen gals are tied to the department store via their Olsenboye collection, which is sold at JCPenney stores.

On a sidenote, Mary-Kate and Ashley have also treated their fans to another installment from their monthly StyleMint T Moment videos, with the January clip available for your viewing pleasure below!
