Oh, H., if you are only smaller, count your blessings. I am almost finished weaning my son, and I have gone from a C to a B. I actually don't mind being a B. What bothers me is that all the skin from my pregnancy and nursing size D is still there,; it's the "filler" that's missing, so I am left with flabby, floppy, squishy sacks of nothing in place of what used to be a pretty good looking pair. I recently went to Victoria's Secret to buy new bras to fit the new me. It took the manager, a sales clerk, and EVERY bra in the store before they finally found one that fit me (the last option they had). The problem was my breasts are so floppy, they kept, well, flopping out the front of the bra every time I bent over. The bra that finally worked for me is made of memory foam, so it contours to my new sad, shape.
It's pretty depressing, but I'm still glad I breastfed. At least a good bra makes them still look good with clothes on!
