I agree with the others, you look lovely, though I understand that you are experiencing a change, something is different, and you don't feel so good about the change. I'm in my fourties, 6 years ago I had my second child, she was big, I had a cezarian too and after that, my belly was never again what it was before, no matter what. Plus, during the last few years, my body started to change in some other different ways that I'm not happy about. I had a feeling that nothing fits me any more, styles that looked so good on me before didn't look right, and what I could find in the stores that I used to like... I had two young children and no time to shop. Then I decided this has to change. Once a week, or once every two weeks, I hired a babysitter to take the children for a couple of hour so I could go and browse the stores.
I left no stone unturned, as Angie says. I tried new things and slowly, I found a new style which I'm happy about.
I got rid of all my pre-pregnancy clothes and stopped comparing my body to what it was before, that helped also. I made peace with my new body. The best advice I can give you from my experience is the same as Lisa's: don't buy too baggy and too big clothes to hide what you don't like, it will only make you feel worse. Good luck and don't forget, this may be a chance to discover something new and unexpected. And try to have fun doing it.
P.S. I really like your blog.
