This Mash-Up Monday, Cybergirls Erika Knight, Jenni Lynn and Daniella Dior team up with Argentinean stunner Celeste for the best in fine leather goods. Erika  is tough in fingerless gloves, and Jenni Lynn's leather skirt could not be shorter. Celeste's leather bracelet makes a subtle statement, while Daniella's vest leaves little to the imagination.
