Size 0 in torrid sizing, which is a 12. However it does has stretch in chest, booty & leg area. Waist doesn’t have as much stretch Could also fit size 14-16 depending on body shape. Short girl approved and Big breast friendly. Smaller chest will need to pin or wear tank under for a more modest look. For reference in photo I’m 220lbs, Height: 5’4, 44C, Size 14-16W
