To care for your Susan top, machine wash it with like colours on a gentle cycle in cold water. Lay it flat or hang it to dry. Make sure to avoid fabric softener, as it damages clothing! The collar and placket contain fusing so we recommend pressing after each wash, especially if you notice any wrinkling or buckling around the collar.
