Your dress or blouse machine washable, but hand washing is preferred. Cold water and gentle detergent will render the best results. Never, under any circumstances, put your Spirit blouse or dress in the dryer. You will be sad. And I cannot fix it. While you can iron your blouse, I think this is unnecessary. Downy Wrinkle Releaser and a few shake does the trick. The 100% cotton weave responds well to steam, also.
