Can you please advise....when would people suggest investing in maternity bras? And how do you gage which size to buy? Say I was a 10B before pregnancy....what sizes do you go to from there? I know it depends, but is a 10B maternity bra the same size as a 10B normal bra? I also know that when the milk comes in after the birth, your boobs get bigger too, so how do you determine what size to buy?

Thanks
Sharon
