We couldn't define (or pronounce) the Pythagorean theorem if our life depended on it, but we know a geometry fetish when we see one. Case in point: the sharp angles and figures of Farahbella's S/S 09 collection, "Calculated Progression." The third collection from husband-and-wife designers Rick and Alnea Miskiv features an interesting, infinitely wearable counter-play between the soft--loose, easy shapes and wispy fabrics—and the severe&mdsah;the sharp angles of a rigid collar or asymmetrical hem, inverted triangle cut-outs, and a dominant dove-gray diamond print that adorns everything from long and lean slacks to a slouchy sack dress. Cute and acute? We dig it.
