This is maternity denim from Chocoa. It was also featured in Aya Kaneko's maternity book. While many maternity pants are skinny, these are straight to wide-legged, and the denim fabric is cute. I wore them for about three months, and I could wear them until my due date, when my belly circumference was around 100cm. They were roomy, so I wore leggings underneath in the dead of winter and stayed warm. I had a very easy delivery!
