These bed sheets by Piglet are made from 100% natural stonewashed French flax, a fabric that’s cozy but breathable, as linen is woven more loosely than cotton. As such, they prove luxurious without being too silky, and natural without being scratchy. Best of all, the fabric just gets softer with each wash. The bundle (which comes with a striped duvet cover, two striped pillowcases, two white pillowcases, a flat sheet and a fitted sheet) offers an effortless but sophisticated look—thanks to its gray stripes on pale ecru, and natural creases. Available in full, queen or king sizes.
