I had terrible trouble finding maternity trousers that were long enough when I was pregnant and ended up having to make do with my usual trousers for as long as possible, then switch to very stretchy ones that still fit under my bump. And also it was over summer so I could get away with normal size maternity crop trousers.
I got really fed up with suppliers offering 'tall sizes' only to find they only meant 33". I needed 34"/35" which I couldn't find anywhere. Long Tall Sally only offered two styles and the stock doesn't come in very often and is limited in number - and now they only do maternity jeans so you can't get work trousers!
So I'm in the process of looking into setting up a UK internet shop with fashionable maternity trousers in the lengths 34", 35" and 36". I wanted to see if any of you tall mums out there think this would be useful (did you have the same trouble) and what sort of styles you'd like to see?
