I wear a 34 D, but could use a DD at certain times of the month.  I only wear minimizers.  I ordered a 34 D and the fit is perfect. This bra has slightly fuller cups which help with a little spill-over in the front.  It's so soft and the back is truly more comfortable.  I literally said, "Ahhhh" when I put it on. I highly suggest you try this bra.  I will definitely stick with this one!  I only have one little complaint; the adjustments on the straps slip a bit by the end of the day.  I might have to put a little stitch in them to make them stay put.
