The Pietra Pants & Shorts are the best of both worlds; a flat front, high-waisted silhouette with the comfort of an elastic waist in the back. For a more defined shape, use structured wovens such as linen, chambray, or lightweight denim or twill (heavyweight wovens may create too much volume at the elastic waist). For a swishy, glamorous look, use rayon challis, tencel, or silk.
