The pants are style Arc as well, the Elle pants. This was my first pair and the fabric probably wasn't quite right. It is a stetch woven but its ok I like the colour.
It all looks a bit wrinkled but I have worn them all day. Forgive the look I really don't know how to pose. I feel very uncomfortable . I wish I had made the tunic a bit longer and the pants slightly bigger.
I have made another 2 pairs of the Elle pants. On the other pants I adjusted the pattern by increasing the crutch so it went over my tummy. They fit better. I really like this pant pattern. I like how the waistband is a separate piece you put on. I feel this makes it fit better.
Happy Sewing !
