This is a maternity pajama. It can be used before and after childbirth. There are no pants. I am 158cm tall, and the length is up to about my knees. There are no buttons on the nursing opening, so I think it's good for those who want to breastfeed, as you can easily take it out! Of course, for those who are giving birth this fall and winter, and for those going into summer, you may need a long-sleeved shirt as hospitals have air conditioning! There is some wear and tear, but if you don't mind, or if you want to buy it cheap, how about it?
