A bed sheet defined by a one-ply woven web of warp yarns and fill yarns having a top and a side panel depending from the top panel. The warp yarns extend in a warp direction through the top and side panel and the fill yarns extend in a fill direction through the top and the side panel. A plurality of fill yarns, warp yarns, or both are a non-spandex, non-core spun elastomeric yarn whereby the bed sheet is stretchable at least along the elastomeric yarns as a contoured bed sheet. In one example, the non-spandex, non-core spun elastomeric yarns are composed of elasterell-p.
