After owing and trying night time nursing bras from most of the main suppliers I came across the Majamas Easy Bra. I love it so much that I have replaced my old worn out ones with these.

Pros: It is such a comfortable bra. Soft fabric. Snug but stretchy fit (I'm 32D/DD and would normally take small but I bought medium as small was way too small). Nice wide elastic chest band. No 'dropping out' when I roll over in the night.

Cons: The price. It's quite a bit more expensive than most other bras.
