As pregnancy progresses and nursing begins, your breast size will fluctuate by the week. To make matters worse, your breasts will feel especially sensitive at certain stages, making comfort as important as proper fit. The most important clothing accessories are the ones that will never be seen. A proper fitting supportive bra is vital during pregnancy and after delivery. Old bras are generally useless during pregnancy because of your expanding physique and engorged breast after delivery.
Lets just say they never quite fit the same again.
Bypass the discount stores and sale racks and have a fitting done by an experienced fitter at a well stocked lingerie department or at a specialty shop. A well seasoned fitting specialist should be able to tell approximately how much extra room and support will be needed. Being fitted for a bra is a service that is provided at no extra charge so take the offer to be fitted and see how good a bra will feel when it fits properly. A good bra is not cheap. You can just buy a regular bra in a larger size, but you may regret it.
