@Lougle - thanks - that is nice although I think that has petal sleeves rather than cape sleeves. It's a good fall back option though.
Thanks also for the Vestair suggestion.
I think maybe that original design is a one off. Part of the reason I like it so much is that a v-neck and cape sleeves would be so flattering particularly if you don't have ultra toned upper arms. I'm suprised more designers don't make similar.
It seems like if there is a cape sleeve it is assumed the wearer must want to cover up totally so they tend to be long tending batwingy and also have very high necks!
