OK, I've had a mini sort out.
sweetkitty: I have 2 size 8 maternity items if you are interested. A pair of dark blue jeans and a very lightweight denim pinafore style dress (both from Dorothy P)
muppetmuggle I have 3 t-shirts which are petite size 8 which I would say are equivalent to size 6. Black, grey and pink from Next. (I'll have another look but most of my stuff is size 8)
Cargirl and moljam - did you want size 6 bottoms? (sorry, I'm getting abit confused now!) I have 3 or 4 pairs of size 6 PETITE trousers (jeans/linen trousers)
If anyone's interested, please let me know!
