Its different up here cos its still warmish during the day, and I get away with wearing DH's shorts (he is a pretty big bloke) and they are very comfy!!!!
But I'm happy to go around the house in my trackies. For appointments I have found really good maternity pants that slip on and go over your bump (yes the entire bit) and while it looks very unfash until you put a shirt on, they are super super comfy... I think I got them from Big W or Target?? I have two pairs.. lifesavers they are... you can dress them up or down...
