I wear spanx dzily. Usually high waisted short and a smoothing tank. Im only 15 pounds from my pre-birth weight but my skin is saggy or just not where it used to be. These slimmers get me comfortably back in my fat clothes. Going to be a while before i see my skinny jeans again! 5'11 178 lbs and i use size C as my normal weight is 160ish. Size 10-12 now. My old size CStill work and i was a comfy size 8.
