My favourite things during winter were long sleeved stretchy T shirts worn with mat jeans. I was in the third tri by then and flowy tops just made me look absolutely enormous and fat (not pregnant).

During summer my favorite was a flowy no sleeved top that had a cami under it. I wore this with 3/4 length mat jeans.

I'm still wearing all my favourite winter stuff around the house even though I don't need to.

I also loved Bonds Belly bands. I'm sure you could make those up easily enough. Towards the end I wore them constantly to extend my usual wardrobe and they were also handy to cover my tummy when breastfeeding.
