The only place I can find them is Next and their stuff doesn't fit me at all. Blooming Marvellous short jeans are a perfect fit, but I need something slightly smarter for a weekend away. They only seem to do short jeans, not other trousers.
When not pg the only places I've found that do trousers that fit are M&S (but they don't do short maternity ones) and Fat Face (no maternity range).
Just to be extra awkward, I need to be able to buy them online - don't live near any sizeable shops.
