Bravissimo fitted me with a Royce one which was okay for a while but I can't stand them now. I'm so sick of the lack of underwires and I hate the fact that my boobs aren't separated at the cleavage, because having no wire means the two cups merge into one.
Missy, two of the ones you've linked don't really have big sizes though and one has double sizes, like 34F/G and I think being that vaguely sized isn't going to be good for mastitis prevention,or fitting really big boobs in general.
My Royce is a 38HH but I think I need to go back down to a 36 since giving birth as it's riding up the back. I hate having to pay out so much for good bras, really bugs me, I was a 34/36H pre-pregnancy so it's not a new problem to me.
I have read that you can buy the clasps online to convert normal bras into nursing ones, I am tempted to get some and test it out with my old wired bras to see if I can do that. I'd love to wear normal bras again!
