Last year, Farley's sexy mobster costume was a big hit with fans. Her long-time boyfriend, Roger Matthews, was dressed to match in a pinstripe suit and fedora. Farley and Matthews are planning to wear matching costumes for this year's Halloween party, as well.

Best known from MTV's hit show, "Jersey Shore," Farley returned to Seaside Heights with new mom and best friend Nicole "Snooki" Polizzi for the spin-off, "Snooki & JWoww," before making a final return to the infamous boardwalk house for a sixth and final season of, "Jersey Shore," which premiered on October 4. The former graphic design student recently launched her own lines of swimsuits, tanning lotions, perfume and skin care.
