In reply to peas65:
I managed to get away with stealing my husband's tops - he's much the same height, but men's tops tended to be broader and longer than women's, so they were OK.
Trousers were much more of an issue - I had a pair of the old, really stretchy Ron Hills that fitted til term, and bought a pair of cropped "outdoor casual" trousers in a larger size with a drawstring waist for warmer weather. And a pair of synthetic jersey maternity trousers.
Can't remember what I did for waterproof trousers, though......
