Hiya
I was about 16 weeks pregnant when I started wearing maternity clothes.
My best-buy was a pair of maternity jeans from Dorothy Perkins, I think they were about �22 and I lived in them. I didn't have a vast maternity wardrobe I just bought a few things that I could mix-and-match.
I read somewhere that the average spend on maternity wardrobe is �900! I might have spent �200, I didn't see the point in spending loads on clothes which would only last 6 months.
Take care & happy shopping x
