I have 3 pairs of winter trousers, 1 pair is for casual, black colored. I used them when I had my 1st child.
I also bought 2 new pairs when they were on sale (in Sept). 1 pair is jeans (about $2xx after discount) and another pair is for formal / not that casual...just in case I need to go to 'drink' (also about $2xx after discount).
For the clothes, I won't spend extra money on it as I will just wear the summer clothes (short sleeves) and wear a coat over it!!! My due date is about mid Jan...so I hope it won't be too cold!!!!
