Have you had a look at the Alexon site (ie - not that awful Monsoon dress)
They have a teal version of that grey dress (more or less)
or actually, this teal one is even nicer and they're both on sale - hurrah!
Or this stunning Jade one at full price
Huh - wonder why all the nicest dresses are in the blue/green spectrum. I reckon they're trying to get me to buy another dress from them...
I take it back - they have that Jade style in sexy sexy red too.
