The Tree Dress by Houdini is a relatively loose-fitting, airy dress made from cooling and drying lyocell, a fiber that is sustainably sourced from fast-growing eucalyptus. It has long sleeves that can be unbuttoned and rolled up and a full-length button placket. It has slits at the sides if you need or want to take a less relaxed stroll. Otherwise, the fabric is pleasantly soft, cooling and moisture-regulating, making it perfect for long summer days.
