Muji maternity pajamas for summer (with nursing access). I wore these for about two days during my hospital stay after receiving them from someone else. The fabric is durable, so there isn't much sign of wear, but there are some minor, faint stains if you look closely. Also, the waist of the pants seems to have stretched out, but it wasn't a problem, especially since my belly didn't go back to normal immediately after giving birth. Please refrain from purchasing if you are looking for a perfect item, as this is a used item. There are no pets or smokers. Thank you very much.
