It was Justin Alexander, I think.
It had a completely smooth, fitted, shaped bodice and the lower half was (what made me decide not to buy it at the time) kind of like a swan.
Not lacey, just lots and lots of triangle(?) shaped pieces of fabric. (Organza?)
I think it might have been called waterfall...
Have tried googling it but can't find it anywhere.
Anyone know of/remember it?
