I was so impressed considering this is half the price at Davids Bridal for the same shaper!! I followed the previous reviews and sized up 2 sizes from my bra's normal band size and down 1 cup. It fit well-slightly snug as I was hoping to keep me in. If you are not well-endowed, you may want to go down 2 cups. I have a large chest but I still plan on adding stick ons for my wedding. I recommend getting a shaping bottom- I am getting a high wasted garter belt to go with it. My dress is a ball gown so that works best for me. I suspect the reviewers saying it was too small are not ordering in comparison with their TRUE bra size which is important to know. If your bra usually fits tight, you probably are ordering the wrong size.
