I am always fascinated how Americans seem to send their underwear to the ship's laundry . Me ? Never , ever , ever , I value the elastic in my knickers to stay elastic and my white bras to stay white . I hand wash in the bathroom sink and hang on the line in the shower or use my hanger that has clothes pegs on it. Only ever used the ship's laundry once for tshirts and they were ruined , never again . Stuff dries overnight in the shower so long as you don't pack heavy thick tshirts . Heck I have even washed jeggings and they dried quickly .
