100% cotton pajama pants only Set of 2 colors: gray and navy Thin cotton material - Color: Gray - Color: Navy - Material: Cotton - Material: Cotton Thank you for viewing. The waist can be adjusted with buttons. These thin long pants are recommended for pregnant women from around spring to autumn. I hadn't bought maternity wear because it was for a short period, but from the later stages of pregnancy, my belly started to show, and pants other than maternity ones became uncomfortable. So, I wore maternity pants only on the bottom and wore my husband's T-shirts on top. It's not new, so there may be some signs of use, but since it was for a short period, I hope the next pregnant woman can spend comfortably at a low price with these maternity pants. Color...
