I usually wear a 18 sometimes 20 I absolutely love this set! fits me perfectly I have wide hips thick thighs a shelf butt wasn’t tight at all I will be buying it again in the pink. the waistband is perfect stays in place all day and it snatches your waist, not like a omg this is uncomfy it just makes u feel secure. one thing that maybe is a con but didn’t really bother me is my boyfriend said it was a bit see through if i touched my toes.
