This season, there have been quite a few designers inspired by the prairie look of the 1970s. At Rodarte, the Mulleavy sisters skipped over Gunne Sax and went straight to the source, creating a modern Little House on the Prairie wardrobe that would make romantic fans of Laura Ingalls Wilder swoon. We know we did. Building on last season's old-timey collection, the designers took their abstract idea of patchwork in a more literal direction, with cut-out calico triangle tops paired with classic circle skirts.
