Designers Tina Lutz and Marcia Patmos of eponymous brand Lutz & Patmos, are following in the footsteps of our friends at Bblessing, Mayle, and Lyell, and exiting the scene (Marcia is set to launch a high end women's line, M.Patmos) with a fashion farewell that we'll never forget. In tandem with their tenth anniversary, the girls have launched a online guest designer shop that includes all of its collabs from the past decade. Since the label was one of the major originators of the "guest designer concept" (hello Target!), you can bet that the pieces will be covetable collector's items, especially as fall '10 is their final season. Plus, Lutz & Patmos will donate $10-50 from each item to charities like Care and Unicef's Children Fund. Look for their remastered signature knits in limited-editions (Sofia Coppola, Christy Turlington, Carine Roitfeld, and L'wren Scott); and of course, we're drooling over our old faves—Natalia Vodianova's 2 Way Dress, Fabien Baron's Cashmere Tee, and Liv Tyler's Cape. Though goodbyes suck, this is one pretty good way to say auf wiedersehen.
