I couldn't tell you from personal experience since the only time I haven't been breastfeeding in the last twelve years, I have been pregnant, but... I have heard that ones breasts will fill back in to a certain extent (I can't imagine that they will ever be in pre-baby shape) after weaning and that it will take 9 months to a year.

In the meantime I have found that a good push up bra can do wonders!
