Made in collaboration with artist Alan Berry Rhys, this T-shirt dress—done in a luxurious, slubbed hemp-silk blend—is patterned with vintage-looking illustrations. It has a padded collar and shoulders, a back loop-and-button closure, and a breezy side slit. Keep your accessories simple so they don't compete with the pattern (chunky sandals and a neutral bag would do nicely).

• 85% hemp, 15% silk
