From Seamwork:
The Jo dress is an oversized, popover shirtdress with fun gathers below the front and back yokes. It features a band collar, partial placket, and a comfortable cocoon silhouette.
This dress moves best in your favorite flowy wovens, like Tencel, rayon challis, voile, lawn, or silk crepe. Or, pick a medium-weight woven for a more dramatic silhouette, like flannel or chambray.
