These fit perfectly.  I ordered the 34 and I am a 32D and they work beautifully.  They are comfortable - no seams digging in, and very well cut so they look nice as well.  The cotton is soft and still give a nice hold, not super strong, but not meant to be.  I cannot recommend them enough.  Fabulous purchase.  I was unable to find anything else even like them anywhere else.  I use them with those little silicone nipple-covers under a top to work or wherever and they look great.  I especially like that the cut has the 'v' in front so that they do not show above the neckline of my shirts, etc.
