Seriously by the time you are pregnant, are you really going to want to wear those old things?
Well, I had lost a lot of weight before getting pregnant the first time and those bigger clothes did come in very handy. I do understand about fashion though, there were some items I just would not wear even though they did fit and other which I wore first pregnancy but not the second.

I think you are all right though, they should just go. I got most of them on special anyway and they have been worn a fair bit. Now to find a garbage bag and pick a charity.
