You certainly do not want to end up spending a lot of money with lots of bras that do not fit on you or your beautiful bodies after the first two weeks of nursing in your drawer. Avoid under-wire bras if possible, I also recommend... including the use of tight bra that can be used for the athletes. Avoid it!
A bra that is too loose can also cause problems for large breasted women. The best option to get maternity bras for large breasts, comfortable and supported kinda bras is to have it installed by a professional. The best online resources I've ever found to solve this such problem is www.nursingbrasforlargebreasts.com. Please check the page. They have excellent choices of bras in various brands and sizes, along with detailed information on how to fulfill orders of them.
