I gave birth to my baby boy on October 1, 2012 (naturally - no C-Section) and the day after I put this baby on before we were released to go home.  I HAD a 25 inch waist prior to giving birth, but my 8.5 lb boy kind of stretched me out.  It was a little bit of a battle getting it on but I felt supported and comfortable the whole time.  I wore this thing day and night for 6 weeks straight and I still wear it on occasion now.  I'm down to 27.5 inches and I'm on my way back to my pre baby shape.  I love the fact that it was very breathable and didn't roll down.

As I was walking out of the hospital everyone kept saying, "you do not look like you just had a baby" it was great.  I recommend buying the pair - after 8 weeks I realized I needed an XS to aid me in my reshaping quest.  I will totally buy this after my next baby (give me two years) but this time I'll be sure to buy a small and an extra small.

One small thing - I found some of the other reviews to be true - after constant use the top lining started to tear.  I sewed it back up and I was good to go.
