Isabella Oliver maternity - Urban dress

[sweetmelody]

Desperately after this dress from last season in a size 2 (10), preferably in a dark colour. I am kicking myself because I was looking out for a size 3 for ages on eBay but then found out how big her clothes come up, so am now after the smaller size.

Any ideas where I could get one (have tried IO but no joy) or anyone have one they want to sell me ?!!
