This shirt was designed with the pumping mom and mom of multiples in mind. With two slits on either side under the first layer, tandem pumping and tandem nursing is not a problem. The sleeves are a stylish mid length, and the material is our signature, buttery soft viscose. Works great under a coat or on it’s own, this shirt is perfect for all seasons. Machine wash in cold water (best to wash inside out) and hang to dry.
