During these tough economic times, countless savvy fashion designers are reconciling the trickle-down-to-the-masses effect—and showing affordable offshoot lines. Joining the ranks of Anna Sui, Thakoon, and several other well-known designers, Laura and Kate Mulleavy, the sister act behind Rodarte, are designing a "GO International" collection for Target (hitting stores December 22).

While this sartorial collaboration is hotly anticipated by fashionistas and recessionistas alike, it's another store to which the Mulleavy sisters are lending their style that has me excited. While team Rodarte is loyal to their California roots and conduct their operation out of L.A., they are additionally broadening their fashion horizons in Paris.

Beginning during Paris Fashion Week (going on as we speak...without me, no less!) and extending until November 7th, ultra-hip rue Saint-Honoré lifestyle store Colette has given Kate and Laura Mulleavy free reign of its upper level, turning it into a showroom of their favorite things. Designed as a sort of pop-up shop cum art gallery, the sister-curators are showing off their favorite music and movies, Rodarte knitted dolls, limited edition jewelry, artwork by Annakim Violette and Sonic Youth’s Kim Gordon, and, most coveted by me, Rodarte for Repetto ballet flats (right).
