This top is good for back & belly support and firming.  It sucks everything in.  Im 53, 150lbs, 3.5 months postpartum, and a large fits well.  Unfortunately, it doesnt have that smooth illusive feel & fabric like most shape-wear; thus, I felt like when friends and family hugged me they could feel its stiffness and edges which takes away from the appeal.  But overall, youll get smooth contours, a slimming effect, and belly support.
