Nursing bra made of stretchy cotton rib material that is soft and comfortable to wear. The back side is made of 100% cotton that is gentle on the skin. It is wireless and does not constrict, and the under elastic does not come into direct contact with the skin. The back style is U-shaped for added stability! You can also adjust the under with a 4-stage hook. It can be used comfortably during pregnancy, when the body is delicate, after childbirth, and during breastfeeding. Breastfeeding is easy by opening the cup with one hand from the chest of the cache-coeur. Can be worn as a set with Matching style shorts and bra cami. Assuming that the stomach and bust will grow during the maternity period, we have developed maternity M and maternity L sizes. If you were M size before pregnancy, choose Maternity M, and if you were L size, choose Maternity L.
