ASOS.com are now stocking cult brand Black Halo, probably most famous for dressing Amanda in Ugly Betty just about every week. She must have the Jackie O dress (£225) in about five colours, though right now we can only get it this side of the pond in black (and only up to a size 12 - that's 'large' apparently). The one shoulder slim belt dress (£240) from the same range is also available, and has been worn out and about by Paris Hilton (but don't let that put you off).
