Long sleeve tee has a 2 way horizontal zipper for nursing and/or pumping access. The fit is relaxed, but not baggy, and I was able to wear this late into my pregnancy. Fabric is 95% cotton, 5% spandex so it has a little stretch. I have also listed in same tee in their “wine” 3 block color way if you would like to bundle. From a smoke free pet friendly home.
