I was just reading about the ideal breast size and shape.   In general, it sounds like 55% of the breast mass should be below the nipple creating a teardrop shape, with the nipple having a slight upward tilt.  I have much more boob above the nipple vs below.   

I'm happy with my overall size, but would like to increase lower half to give perkier look.  I have been trying to locate the noogle cups lower, but seem to slide up when I  increase pressure.  Any suggestions?
