Multicolor V-Neck, 135€

What was once a textile factory is now a light-filled, 6,000-square-foot charitable shop filled with an eclectic mix of clothing, stationery, home goods, gardening tools and more, all of it gorgeously designed and contributed by its makers. Sales of everything from Marni and Stella McCartney tops to '30s-inspired light switches benefit a youth co-op in Madagascar.
