This product is a maternity product, but they didn't seem to add any extra fabric for the ... ummmm... maternity party of your body.  Also, maybe it is made for Japanese women because on me, these pants fit like capris (I am 5'7")  I am wearing these as pajamas now, but the baby was born 10 months ago.  I couldn't wear them when I was preggers.

Don't waste your money.  Go to Pea in the Pod and order their pajamas with "modal" as the fabric.  In fact, anything with "modal" is fantastic for maternity wear.

Congratulations on your pregnancy and I wish a pleasant labor and birth experience.
