I am way up to a 12F now. Weird size. I had a look at the slimform bras but they didn't come in my size so I had to go to Myer and get triumph bras. I find them really comfortable and supportive. They are expensive though, around $55. The lady who fitted me kept on saying, once your milk comes in you won't be comfortable anyway so whatever bra you buy will be awful then. LOL
