HerRoom Response: The sizing suggestion was to only go down a cup size if you are between cup sizes. According to your comment you went from a 36HH to a 40I - this is an increase in 2 band sizes and 3 cup sizes.

HerRoom Response: IF by "poking up" you mean the wires in the center are pointing away from your sternum, this is a classic symptom that your cup size is too small - your breasts are pushing the underwires forward. I would suggest going up a cup size.
