Only rinsed with water. This bloomer set-up is easy to wear, with no buttons on the neckline and a drawstring neckline. These bloomer pants are designed with a rounded volume and fit to allow for comfortable movement even when wearing a diaper. I'm selling these to organize my closet! I'll wear them if they don't sell, so I won't be offering a significant discount. However, I will offer a discount for multiple purchases ◎
