I just bought one of those maternity crop top bras from shop at home http://www.shopathome.com.au/. It's great! I'm usually an AA-A cup and have trouble finding a maternity bra as they all start with B cups... too big for me
This one is so comfy it will be really easy to sleep in... seems to be reasonably supportive without being too tight.
