Channy, Mrs LA etc, regarding maternity clothes, I splurged and bought myself a nice pair of maternity jeans (they cost me $70) but it was worth it as when I was going out I felt normal! I got them from Angel maternity in castle hill sydney. They are online too. They have a clearance page, so you can pick up some bargains there maybe.
I found Kmart was my secret shopping destination..... I didn't go anywhere near their maternity clothes but found a few pants and skirt that fit (elastic sided!). So check out there you might find something you like and makes you feel pretty!
