I thought I would use this more but it just wasn't comfortable and it showed under clothes.  So I can't speak to whether it works or not, but looking back I probably would have saved my money based on how little I actually felt compelled to put this on.  When I did have it on I felt really held-in-place, so that's nice (especially after a c-section when you feel like a squishy mess).  I'd say, buy it if you think you'll actually commit to regularly wearing it but be warned it does show through clothes.
