I wore this shirt throughout my nursing journey with my son. I felt so put together and confident, not to mention the sweet mint and white colors. The side tie and hidden zippers are the perfect details. XS measures 21” length, 17.5 chest Description from website: MOMS LOVE: The FLATTERING FIT, sleeve length (a big longer), and the QUALITY cotton fabric! NURSING ACCESS: The zipper is hidden between the stripes. This tshirt has one long horizontal nursing zipper under the chest (pulls on both sides). FABRIC: 95% Cotton, 5% Spandex (washes great!)
