I've searched the boards and seen some previous threads on nursing bras for large chests - but I'm wondering specifically what those of you who are, ahem, "blessed" in that area wore immediately postpartum for a few weeks until your milk comes in.

I keep hearing that I shouldn't buy nursing bras until I know what size I'm going to be, but I need something to wear for the first few weeks. And I don't want to spend a lot of money on something that may not fit pretty soon after. Problem is, all the cheapo, stretchy nursing bras you find at Target or wherever come nowhere close to fitting - even the XL size barely covers half my boobs and provides zero support.

Any suggestions?

ETA: I was a 34G pre-pregnancy and while I haven't been measured since, I know they're definitely bigger now... so that's the kind of size I am talking about!
