BNWT - I have two pairs. I have a 15 16W. They have pretty good stretch so I’d say size down. The W is plus size. The 15 transfers back to the juniors size chart. The thigh is a little bigger for the plus size. Rise (size 7): 11'' Rise (size 16W): 12'' Inseam: 34.5'' Fabric: 52.2% Cotton, 21.5% Rayon, 23.4% Polyester, 2.9% Lycra
