Clever construction forms Robert’s racer-back top: After the I-cord neck straps have been joined, the separate back strap is folded over the seam and sewn in place. The deep band of ribbing at the lower edge-which streamlines the close, cropped silhouette- flows into the cable-and-rib pattern at the bodice. With its purple, gray and yellow palette, Taiyo Sock color way #S30 complements the sporty look.
