I used to have pretty impressive puffies, but as my breasts gradually went from a B to a C cup years after my initial breast growth... and as that happened, they kinda flattened out against the curve of the breast.
still have 'puffy-sized' areola diameters though

just a hair wider than a soup can top.
well, unless it gets cold, or arousing, then they shrink down some, but stay wider than 50cent pieces.
its my impression that "puffies" look kinda "pubescent". not a criticism, just an observation, based on watching my own (and some other girls I've known) breasts grow in.
