I have the same issues and I have found the Triumph ones to be the best in terms of comfort, price and availability. They have a few maternity ones and I just buy them in a couple of colours- they usually have peach, white and black. They are really practical but not the prettiest in the shop. I really don't like Hot Milk at all and many others ie Elle McPherson etc don't fit. The other thing I have done is gone to a specialist lingerie shop where they altered some for me ie I got some Lovable in my cup size but too big in the back which they took a few days to shorten the back. I don't like buying bras online as I have such issues getting them right in real life that I know I can't just buy from measurements online!
