This set is so comfortable. I'm a true size medium, but I sized down to the small based upon the try-on model as we have similar measurements. The stretch is amazing, but still holds things in and it's squat proof. If I went with my true size I wouldn't have had the kind of compressive support I prefer in the top, but sometimes I'm worried my high impact workouts would cause the top to ride up for under-boob peek-age. I do wish it had removable cups in the bra for added support and modesty coverage. The color is absolutely gorgeous!!
