I bought cheaper Jc Penny bras the first time I went up a cup size while I was pregnant, and was so uncomfortable. They were ok, but not great. The next time I had to buy them I got nursing bras from motherhood maternity. They weren't really much more expensive than the Vanity Fair or whatever they were. I knew I might need to go up another size when my mik came up, but since I was close to due date I figured I'd start there since I was having to buy them anyway (I couldn't stick it out any longer, I was miserable in them). I didn't have to buy them a third time, thank goodness, because the nursing bras will expand. I ended up going up 3 cups sizes by the time I delivered, it was ridiculous, I was in a G. Bras are too important to get cheap uncomfortable ones, to me anyway.
