WOW!  I am completely surprised at how well these actually work.  I tried a number of adhesive bras for my summer strapless dresses and found none to give a good lift or they didn't stick.  I was skeptical when I ordered these, but I had tried everything else, so why not?  They not only stick well (and comfortably) - they actually lifted by chest to provide a very nice push up effect.  I am a 36D and bought the C/D size.  I am extremely pleased with my purchase.  It lifted by chest by about a full inch.  Definitely worth the money and the perfect solution for summer dresses.
