It looks like he drew baggy pants similar to the kind he gave Ghosthunter and the Designer. Baggy from the knees down and tucked into the tops of the boots.
Her jacket also fits poorly at the waist. No one is drawing Barbara now like a superhero you'd have confidence in. She looks meh standing in-between the powerful-looking Nightwing and Spoiler in that splash panel in #117.
On the other hand, he also made Jace's suit ill-fitting and it should be anything but.
