Despite a reputation for being severely shallow, Miamians really do love making a difference in the world--especially while making themselves look fabulous in the process. We've been given the insider's heads up to JustOneFrickinDay.com, a charity founded by the current face of Lancome, Elettra Wiedemann (daughter of Isabella Rosselini), which is working to equip a hospital in Kigutu, Burundi with solar energy for the term of its existence. The Italian stunner has enlisted Chris Benz, Phillip Lim, House of Diehl, Giambattista Valli, Rogan and Rag & Bone to come up with Africa- and energy- inspired t-shirts to be sold via the website starting August 25th. Elettra is already looking forward to a second round of tees which already has Yigal Azrouel on board and Miami's own golden boy, Ungaro designer Esteban Cortazar interested. Word on the street is that Jennifer Aniston loved our fair city so much that she said she'd only buy Cortazar's tee in homage.
