Catherines designs for women sized 16–38 and offers 0X–6X sizing. Their size chart maps 0X to numeric 14–16, 1X to 18–20, 2X to 22–24, 3X to 26–28, 4X to 30–32, 5X to 34–36, and 6X to 38.
Materials vary by style. Jacket and pant bodies commonly use polyester/spandex blends (for example, 96% Polyester/4% Spandex or 98% Polyester/2% Spandex). Tanks are often made from Suprema stretch-cotton (commonly 95% Cotton/5% Spandex). Some pants use a cotton/polyester/spandex blend (for example, 66% Cotton/32% Polyester/2% Spandex).
Regular lengths: jacket 34", tank generally 28" (some tank listings note 30"), and pant inseam 30". Petite lengths: jacket 32", tank 26", and pant inseam 27".
Pants include both pull-on and traditional closures. Some pull-on styles have a covered elastic waistband and a relaxed leg for easy wear; other styles feature a zip fly with button closure and a contour waistband with spandex for shaping and recovery. Fit options include straight-leg and high-rise silhouettes.
Listings indicate the pieces are designed for plus sizes, using extended sizing charts (0X–6X with numeric mappings). Design choices for plus proportions include longer body lengths, relaxed fits, and contour or elastic waistbands with stretch to provide comfortable shaping and recovery.
