thanks guys for all your suggestions,
littleweasel I also really really love the shimmer, even though I guess I'd do it with a diferent lace pattern in the back, and maybe more rounded ruffles at cuffs.
And nevermore, I agree very much with you on the boobholder, I had kind of the same idea about adding long sleeves. Have you got a pic of yours somewhere ? I'd love to see the result with you thin mohair yarn.
